โฆ Synopsis
The chiral and stereoselective synthesis of (+)-lactacystin 1, the first non-protein neurotrophic factor having an ct,~t-disubstituted a-amino acid structure, is described. The highly functionalized y-lactam portion possessing a tetra-substituted carbon with nitrogen in I was effectively constructed from D-glucose using allylic trichloroacetimidate rearrangement (Overman rearrangement) as the key reaction.

A rather facile stereoselective total synthesis of (9S)-9-dihydroerythronolide A starting from D-glucose was achieved via coupling of Cl-C6 and C7-Cl5 segments and subsequent macrolactonizotion. The well known macrolide antibiotic erythromycin A (1) has been an attractive synthetic target for moder
