Olivanic Acid Analogues. Part 1. Total Synthesis of the 7-Oxo-1-azabicyclohept-2-ene-2-carboxylate System and Some Related β-Lactams

4-Allylazetidin-2-one, prepared from penta-1,4-diene and chlorosulphonyl isocyanate, has been used to synthesise the parent 7-oxo-1-azabicyclohept-2-ene-2-carboxylate system of the naturally occurring olivanic acids, using an intramolecular Wittig reaction to construct the 2,3-double bond.Cyclisation of ketones derived from the 4-allyl grouping produced 3-substituted derivatives, while use of the azetidin-2-one prepared from hexa-1,5-diene and chlorosulphonyl isocyanate has given the homologous 8-oxo-1-azabicyclooct-2-ene system.
