Optically active 3,4-disubstituted 2-azetidinones have been prepared in good yield by the annelation of Schiff bases from D-glyceraldehyde acetonide with acid chlorides (or equivalent) and triethylamine.The utility of this enantiospecific synthesis was ex

Stereochemical aspects of the Bose reaction (formation of α-azido-β-lactams from an activated form of azidoacetic acid and imino compounds in the presence of a base) are examined.Substituted β-lactams prepared by stereocontrolled synthesis (including enantiospecific synthesis) are shown to be useful intermediates for β-lactam antibiotics, sugars, alkaloids and other natural products.A stereospecific synthesis of an optically active 3-aminosugar related to gentosamine starting from a β-lactam synthon is described.
