Rational Design of Highly Diastereoselective, Organic Base-Catalyzed, Room-Temperature Michael Addition Reactions

Via the rational design of a single-preferred transition state, stabilized by electron donor – acceptor-type attractive interactions, structural and geometric requirements for the corresponding starting compounds have been determined. The Ni(II) complex of the Schiff base of glycine with o-[N-alpha-picolylamino]acetophenone, as a nucleophilic glycine equivalent, and N-(trans-enoyl)oxazolidin-2-ones, as derivatives of an alpha,beta-unsaturated carboxylic acid, were found to be the substrates of choice featuring geometric/conformational homogeneity and high reactivity. The corresponding Michael addition reactions were found to proceed at room temperature in the presence of catalytic amounts of DBU to afford quantitatively the addition products with virtually complete diastereoselectivity. Acidic decomposition of the products followed by treatment of the reaction mixture with NH4OH gave rise to the diastereomerically pure 3-substituted pyroglutamic acids.

Total synthesis of (+)-suaveolindole: Establishment of its absolute configuration

This communication describes two approaches toward the total synthesis of (+)-suaveolindole. The initial strategy uses a 6-exo-Heck cyclization to generate a transient sp3 carbopalladate. This intermediate was successfully coupled with an indole 3-stannane to assemble the majority of the carbon framework of the natural product. However, due to problems described herein, this interesting route was not viable. To reach our target, lessons learned from the first strategy directed us to develop a significant extension of the Ireland ester enolate rearrangement in which the tetra-substituted isopropylidene group and the alpha-disposed carboxymethyl function are introduced in a single event. This key reaction enables a remarkably concise inaugural synthesis of (+)-suaveolindole. Copyright

One-pot synthesis of alkynylthiocyanates by phase-transfer reagent

Thiocyano-group widely exist in natural products and drug structures. A novel one-pot synthesis of alkynylthiocyanates from terminal alkynes, [hydroxy(tosyloxy)iodo]benzene and potassium thiocyanate by phase-transfer reagent involving the hypervalent iodine intermediates in transition metal-free conditions was developed. The internal alkynylthiocyanates could be used to synthesize some important compounds such as 5-thiocyanato-1,2,3-triazoles and (Z)-alpha-thiocyanato-vinyl trifluoromethanesulfonate.

Stereoselective Diels-Alder reactions of 3-phosphonopropenoyl derivatives of 1,3-oxazolidin-2-ones

Dienophiles of the general structure (EtO)2P(O)CH{double bond, long}CHCOX have been prepared, where X represents an oxazolidinone chiral auxiliary. Use of the (S)-4-isopropyl-5,5-diphenyl-1,3-oxazolidin-2-one auxiliary gave Diels-Alder adducts with several cyclic and acyclic dienes. The crystal structures of the main cyclohexa-1,3-diene and 2,3-dimethylbutadiene adducts formed during reactions in the presence of dialkylaluminium halides are consistent with a reaction, which is stereoselectively endo with respect to the carbonyl group and occurs on the less hindered face of the dienophile when aluminium is chelated between the two carbonyl groups.

The discovery of long-acting saligenin beta2 adrenergic receptor agonists incorporating a urea group

A series of novel, potent and selective human beta2 adrenoceptor agonists incorporating a urea moiety on the terminal right-hand side phenyl ring of (R)-salmeterol is presented. Urea 9j had long duration of action in vitro on guinea pig trachea, and also in vivo similar to that of salmeterol. It had lower oral absorption and bioavailability than salmeterol in both rat and dog. It had a turnover ratio similar to salmeterol, with no evidence for formation of any aniline metabolites in human liver microsomes and hepatocytes. However no crystalline salts suitable for inhaled delivery were identified.
