A stereoselective synthesis of a key intermediate to 1β-methylcarbapenem via aziridine ring-opening reaction

A stereocontrolled synthesis of azetidinone 3 as a key intermediate to 1β-methylcarbapenem 2 has been achieved via iodoamidation of trichloroacetimidate prepared from (Z)-olefinic allylic alcohol 6, aziridine ring-opening reaction with cyanide nucleophile and a tandem β-lactam formation.
