An operationally simple, inexpensive and efficient procedure for benzylation of aldehydes in wet medium has been developed that was mediated with low valent copper, prepared in situ through spontaneous reduction of CuCl 2-2H2O with magnesium in situ. Notably, copper mediated benzylation of 3h took place with good syn selectivity that was opposite to that for the corresponding Grignard addition. Finally, homobenzyl alcohol 5a was elegantly transformed into a known protease inhibitor synthon I. ARKAT USA, Inc.
Enantiodivergent, catalytic asymmetric synthesis of γ-amino vinyl sulfones

A set of diversely substituted N-Boc-γ-amino vinyl sulfones has been prepared by a four-step procedure from readily available, highly enantiopure anti-N-Boc-3-amino-1,2-alkanediols. This new route, which does not depend on the accessibility of α-amino acids as starting materials, is noteworthy for its efficiency, for its generality, and for the fact that both enantiomers of a given γ-amino vinyl sulfone can be obtained with equal ease.
Synthesis of conformationally restricted mimetics of γ-turns and incorporation into desmopressin, an analogue of the peptide hormone vasopressin

Mimetics of tripeptides adopting inverse and classical γ-turn conformations have been designed and synthesized by an enantioselective approach and then incorporated in an analogue of the hormone vasopressin. In the mimetics one of the amide bonds of the γ
