Abstract

Glyoxal is efficiently transformed into the chiral animals bearing the hydrazone functionality and . These compounds react under complete diastereocontrol with various organolithium reagents, affording chiral hydrazines – . Reduction with Raney nickel leads to aminal protected α-aminoaldehydes, which, in turn, are easily hydrolyzed to the free chiral aldehydes (after tBoc protection of the amine). ...
