A series of highly efficient organocatalysts have been derivedfrom naturally available amino acids for carrying out enantioselectivedirectaldolreaction in both organic and aqueous medium. The aldol products were obtained in high diastereoselectivities (up to 99:1) and enantioselectivities (up to >99% ee) for a broader range of substrates using 1 mol % of a catalyst. The results demonstrate that
3-oxazolidine (4-oxaproline) derivatives starting from serine and threonine is described which avoids the use of toxic solvents or reagents. Elaboration of these compounds allows significant improvement in the handling of serine and threonine during the multigram preparation of oligopeptide structures and affords versatile chiral building blocks for the organic synthesis.
A novel series of neutral thrombin inhibitors has been developed using a selection process based on docking experiments and property calculations and predictions.
