SYNTHESIS OF 6-(1-HYDROXYETHYL)-1,1-DIMETHYL-1-CARBA-2-PENEM DERIVATIVES VIA DIECKMANN-TYPE CYCLIZATION

Three diastereomers of 4-(1,1-dimethyl-2-propenyl)-3-hydroxyethyl-2-azetidinones 2, 3, and 11 were obtained by the reaction of acetaldehyde with the enolate of the silyl azetidinone 5 and dilithiated intermediate 10.The trans isomers 2 and 3 were converte
