, p. 67 - 83 (2007/10/02)
Four different isocephem analogs have been synthesized.The key step in the construction of the bicyclic ring involves an anionic 4+2 cyclization.The lithio derivative obtained from a suitably protected N-carboxymethyl-2-azetidinone was condensed with carb

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.
