Recent advances in synthesis of functionalized beta-lactams through cyclization of N-propargyl amine/amide derivatives

beta-lactams have attracted a significant attention due to their potential biological activities and wide variety of synthetic applications. Developing novel and efficient methods for construction of functionalized beta-lactams has been the subject of a number of papers in recent years. N-Propargyl amines/amides are one of the most specific class of alkynes having diverse reaction patterns. It is well known that they can undergo a number of cyclization reactions to produce various significant nitrogen containing heterocycles. This review surveys literature methods for the synthesis of highly substituted beta-lactams from simple and easily available N-propargyl amine/amide derivatives from 1991 to 2017.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 497-25-6 is helpful to your research. Reference of 497-25-6

Total synthesis and biological activity of natural product Urukthapelstatin A

Herein we report the first total synthesis of the natural product Urkuthaplestatin A (Ustat A) utilizing a convergent synthetic strategy. The characterization and biological activity match those of the previously published natural product. Interestingly, several intermediates, including the linear and serine cyclized precursors, show a 100-fold decrease in cytotoxicity, with IC50’s in the low micromolar range. These data indicate that the rigidity and the consecutive aromatic heterocyclic system are responsible for the biological activity.

Loss of the tert-butyloxycarbonyl (Boc) protecting group under basic conditions

Reaction of 3, the N-Boc, O-tosyl derivative of phenylalaninol, with base leads to loss of the Boc and tosyl groups and formation of oxazolidinone 9. Similar reactions have also been examined. A mechanism to explain loss of the Boc group under basic reaction conditions is proposed.

Design and synthesis of the stabilized analogs of belactosin A with the unnatural cis-cyclopropane structure

The belactosin A analog 2a, having the unnatural cis-cyclopropane structure instead of the trans-cyclopropane structure in belactosin A, is a much more potent proteasome inhibitor than belactosin A. However, its cell growth inhibitory effect is rather lower than that expected from its remarkable proteasome inhibitory effect, probably due to its instability under cellular conditions. We hypothesized that the instability of 2a was due to chemical and enzymatic hydrolysis of the strained beta-lactone moiety. Thus, to increase the stability of 2a by chemical modification, its analogs with a sterically more hindered beta-lactone moiety and/or cyclopropylic strain-based conformational restriction were designed and synthesized, resulting in the identification of a stabilized analog 6a as a proteasome inhibitor with cell growth inhibitory effects. Our findings suggest that the chemical and biological stability of 2a is significantly affected by the steric hindrance around its beta-lactone carbonyl moiety and the conformational flexibility of the molecule.

Synthesis of a novel series of 2,3,4-trisubstituted oxazolidines designed by isosteric replacement or rigidification of the structure and cytotoxic evaluation

We have previously reported on a study of the structure-activity relationship in a series of 2,3,4-substituted oxazolidines recently discovered by our group varying the substituent at the ring or stereochemistry of the oxazolidine ring. We discovered the cytotoxic and pro-apoptotic potential of compounds 1 and 2 with good selectivity against cancer cell lines. In the present study we describe the synthesis and cytotoxic evaluation against cancer cell lines (HL60, JURKAT, MDA-MB-231 and LNCaP) of a series of oxazolidines designed by isosteric replacement or rigidification of the oxymethylene spacer of compounds 1 and 2. Alkenes 3 and 4 retained the activity against MDA-MB-231 cells and they were more active on HL60, JURKAT and LNCaP cells. Considering LNCaP cells, E-isomer 4 was at least 7 times and about 3 times more potent than lead 1 and Z-isomer 3, respectively. Compound 4 exerted significant activity against LNCaP with IC50 in the low micromolar range (11 muM) without affecting VERO cells and PBMC proliferation (IC50 > 100 muM) indicating its low toxicity to normal cells.

Stereoselective oxindole synthesis by palladium-catalyzed cyclization reaction of 2-(alkynyl)aryl isocyanates with amides

A new cyclization reaction occurred on treatment of 2-(alkynyl)aryl isocyanates with amides in the presence of a palladium(0)/diphosphine catalyst to stereoselectively form 3-(amidoalkylidene)oxindoles. A carbon-nitrogen bond as well as a carbon-carbon bond were simultaneously introduced onto the alkyne moiety to construct an oxindole skeleton with stereoselective placement of the amino substituent cis to the carbonyl group.
