Various heterofunctionalized acetaldehydes were successfully employed in an amine-catalyzed asymmetric cross-aldol reaction, affording a variety of synthetically useful 1,2-difunctionalized compounds such as 1,2-diols and 1,2-aminoalcohols. With this method, both syn- and anti-1,2-difunctionalized compounds were obtained from the same set of reactants by using the appropriate amine catalyst.

Herein we report a series of novel chloramphenicol amine derivatives as aminopeptidase N (APN)/CD13 inhibitors. All compounds were synthesized starting from commercially available (1S,2S)-2-amino-1-(4-nitrophenyl) propane-1,3-diol. The preliminary biologi

Sphingosine-1-phosphate (S-1P) derivatives such as threo-(2S,3S)-analogues, which are C-3 stereoisomers of natural erythro-(2S,3R)-S-1P, have been synthesized starting from l-serine or (1S,2S)-2-amino-1-aryl-1,3-propanediols (6). threo-(1S,2R)-2-Amino-1-aryl-3-bromopropanols (HBr salt) have also been prepared from 6. The threo-S-1Ps and the threo-amino-bromide derivatives have shown potent inhibitory activity against Ca2+ ion mobilization in HL60 cells induced by erythro-S-1P, suggesting that these compounds would compete with cell surface EDG/S1P receptors.
Synthetic studies on d-biotin. Part 7: A practical asymmetric total synthesis of d-biotin via enantioselective reduction of meso-cyclic imide catalyzed by oxazborolidine

A novel and convenient method for the stereoselective synthesis of d-biotin 1 starting from the commercially available cis-1,3-dibenzyl-2- imidazolidone-4,5-dicarboxylic acid 2 has been developed. The key features of this synthesis include the enantioselective reduction of a meso-cyclic imide, mediated by a chiral oxazborolidine catalyst, derived from (1S,2S)-(+)-threo-1- (4-nitrophenyl)-2-amino-1,3-propanediol and the direct introduction of a C 5 side chain to the (3aS,6aR)-thiolactone through a modified di-Grignard reaction. Enantioselectivities of 98% in the oxazborolidine- catalyzed asymmetric reduction process have been achieved.
