Synthesis of Novel .beta.-Lactam Core Structures Related to the Penam and Penem Antibiotics
摘要:
The synthesis of a structurally new class of penicillin- and penem-type ring systems is described which is based on a sequential imine-ketene cycloaddition reaction and halogen-induced sulfide cyclization process.
