Polyhydroxy amino acid derivatives via β-lactams using enantiospecific approaches and microwave techniques

Enantiospecific synthesis has been developed for α-hydroxy β-lactams of predictable absolute configuration starting with readily available carbohydrates. Stereospecific approaches and microwave assisted chemical reactions have been utilized for the prepar

Studies on Lactams. 81. Enantiospecific Synthesis and Absolute Configuration of Substituted β-Lactams from D-Glyceraldehyde Acetonide

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
