Olivanic Acid Analogues. Part 3. Total Synthesis of C(6α)-Methoxy-substituted 7-Oxo-1-azabicyclohept-2-ene-2-carboxylates

The reaction of the dianion of 4-allylazetidin-2-one with oxygen gave hydroxylation at the C(3)-position.This intermediate has been converted via the phosphorane (9) into the 6α-methoxyazabicycloheptene (13), which was subsequently functionalised with a C

TOTAL SYNTHESIS OF THE 1-CARBAPEN-2-EM AND 1-CARBACEPHA-1,3-DIENE SYSTEMS

The total synthesis of the 1-carbapen-2-em and 1-carbacepha-1,3-diene systems via an internal aldol condensation of enolisable oxo derivatives of azetidinones is described.
