Synthesis of an enol-ether of a cyclopropanone from a diazoalkenylether: a novel class of compound
Abstract
Irradiation of 1-diazo-2-methoxy-3-methyl-1-phenylbut-2-ene (4), prepared from the p-toluenesul-phonylhydrazones (3) of 2-methoxy-3-methyl-1-phenyl-but-2-en-1-one (2), yields 1-methoxy-3,3-dimethyl-2-phenylcyclopropene (5).
