Azetidinone alcohol disulfides and process for cyclization |
| abstract |
Azetidinone alcohol disulfides are synthesized by reduction of the corresponding aldehydes. The azetidinone alcohol disulfides are the substrates for a process which cyclizes these compounds to 1-oxa β-lactam compounds, employing a cyclizing reagent chosen from the class consisting of divalent mercury salts or trivalent phosphine compounds. The 1-oxa β-lactam compounds produced by this process are intermediates in the synthesis of 1-oxa β-lactam antibiotics. |
