(Chemical Equation Presented) A new partner: Potassium alkenyltrifluoroborate salts undergo coupling with amides to give enamides in the presence of a Cu(OAc)2 catalyst and under mild oxidative conditions (see scheme). The air- and water-stable alkenyltrifluoroborate salts offer a convenient alternative to alkenyl halides as cross-coupling partners. A range of amides undergo coupling including cyclic amides, imides, and carbamates as well as benzamides.

(Chemical Equation Presented). Conjugate addition of heteroatom nucleophiles to carbon-carbon double bonds conjugated with a strong electron-withdrawing group is one of the most important new bond-forming strategies in synthetic organic chemistry. Among the methods for these Michael additions, Lewis acids have shown the best promoter activity, and in particular, the use of reagents impregnated over inorganic supports is rapidly increased. With the increase of environmental consciousness in chemical research, the solvent-free Michael addition has attracted our attention. In continuation of our ongoing program to develop synthetic protocols utilizing cerium trichloride, we report an extension of the CeCl3·7H2O/NaI combination supported under solvent-free conditions to promote heteroatom Michael addition. Using neutral alumina (Al2O3) as solid support permits us to circumvent some of the problems associated with the procedure where the inorganic support is silica gel. The CeCl 3· 7H2O/NaI/Al2O3 system works well for hetero-Michael additions utilizing weakly nucleophiles such as imidazoles and carbamates, and also the reaction proceeds with good yields in the case of Michael acceptors different from alpha,beta-unsaturated carbonyl compounds. An important synthetic application of this our methodology is the intramolecular aza-Michael reaction in producing 4-piperidinone derivatives, which are of interest as synthetic intermediates toward important classes of heterocycles.

A straightforward multicomponent Knoevenagel-aza-Michael-cyclocondensation reaction involving readily available hydroxamic acid-derived from naturally occurring alpha-amino acids allows a diversity-oriented synthesis of novel isoxazolidin-5-ones possessing an N-protected alpha-amino acid pendant with good to high diastereoselectivities thanks to a match effect with a chiral organocatalyst. These diversely substituted heterocycles, easily isolated as a single diastereoisomer, proved to be versatile platforms for the formation of an array of alpha/beta-dipeptide fragments.

Catalytic C-H amination reactions enable direct functionalization of non-activated C(sp3)-H bonds with high levels of regio-, chemo- and stereoselectivity. As a powerful tool to unlock the potential of inert C-H bonds, C-H amination chemistry has been applied to the preparation of synthetically challenging targets since major simplification of synthetic sequences are expected from this approach. Pushing C-H amination to its limits has led to a deeper understanding of the reaction mechanism and scope. In this review, we present a description of the specific challenges facing catalytic C-H amination in the synthesis of natural products and related compounds, as well as innovative tactics created to overcome them. By identifying and discussing the major insights gained and strategies designed, we hope that this review will stimulate further progress in C-H amination chemistry and beyond.

A series of chiral C2-symmetric compounds was prepared from readily available alpha,omega-diacyl chlorides and optically pure 2-oxazolidinone derivatives.Following preparation of the asymmetrically pure bis-oxazolidinone derivatives (6a-d, 11, 13, and 20), we prepared the dienolate of these compounds and quenched the reaction mixture with electrophiles such as iodomethane, allyl iodide, and benzyl bromide.Compounds 14a-e, and 15 were isolated with diastereomer ratios in excess of 9.8:1.If the chain length between the two carbonyl atoms was sufficiently small, dialkylation did not occur, but instead, provided cyclization products 18, 19, and 21.Mono-alkylated products 22a-c were prepared from 6c or 6d in modest yield.Unsymmetrical dialkylated compound 23 was prepared in 50percent yield from 22b.

In an article，Which mentioned a new discovery about 16251-45-9

Small molecules that induce or stabilize the association of macromolecules have proven to be useful effectors of a wide variety of biological processes. To date, all examples of such chemical inducers of dimerization have involved known ligands to well-characterized proteins. The generality of this approach could be broadened by enabling the discovery of heterodimerizers that target known macromolecules having no established ligand, or heterodimerizers that produce a novel biologic response in screens having no predetermined macromolecular target. Toward this end, we report the construction of a diversified library of synthetic heterodimerizers consisting of an invariant ligand that targets the FK506-binding protein (AP1867) attached to 320 substituted tetrahydrooxazepines (THOXs). The THOX components were generated by a combination of liquid- and solid-phase procedures employing sequential Mitsonobu displacements to join two structurally diversified olefin-containing monomers, followed by ruthenium-mediated olefin metathesis to effect closure of the seven-membered ring. The 320 resin-bound THOX ligands were coupled in parallel to AP1867, and the products were released from the resin to yield candidate heterodimerizers in sufficient yield and purity to be used directly in biologic testing. A representative panel of 25 candidate heterodimerizers were tested for their ability to pass through the membrane of human fibrosarcoma cells, and all were found to possess activity in this tissue culture system. These studies pave the way for further studies aimed at using small-molecule inducers of heterodimerization to effect novel biological responses in intact cells.

The unusual sphingoid base 5-hydroxy-3-sphingenine was identified in the hydrolysate of brain sphingolipids more than 40 years ago. We present here the first synthesis of the 5R and 5S diastereoisomers of the N-acyl derivatives of 5-hydroxy-3-sphingenine, 2 and 3, respectively, which represent regioisomers of (2S,3R)-ceramide (1). The key steps include the synthesis of a,beta-unsaturated ketone intermediates 4 and 5 from N-Cbz- and N-Boc -L-serine and diastereoselective reduction of the enones. The configuration at the new carbinol center was deduced by proton NMR analysis of (R)- and (S)-Mosher [methoxy(trifluoromethyl)phenylacetate] ester derivatives. Ceramide analogues 2 and 3 showed a markedly higher antiproliferative activity than 1 on MCF-7 cells.
