Abstract

Communications to the Editor cyclohexanoneb mCHO 62a a Precursor enamidines 3 were cleaved to product aldehydes by hydrazinolysis with 1, l-dimethylhydrazine (see procedure of ref 9) followed by acid hydrolysis of methiodides obtained from the intermediate dimethyhydrazones (Corey, EJ; Enders, D. Tetrahedron Lett. 1976, 3). Prior to addition to lithiated 2, 2 equiv of HMPA were added at-78" C. This procedure was found ...
