Thienopyrimidines as hetryl moiety in 2-azetidinones: Synthesis of 4-hetryl-2-azetidinones

A Facile and efficient method for the synthesis of 4-hetryl substituted β-lactams 1 have been reported from substituted thienopyrimidinone 2b, which in turn was prepared from appropriately substituted 2-amino-3-carboxamido thiophene 10. The structures of
