Publikováno v: Synthetic Communications. 7:261-268

We have recently reported the facile preparation of C(α)-multiple anions of oximes2, phenylhydrazones3, hydraxones4, and acylhydrazones5. In each case the C(α)-carbanion reacted with electrophilic reagents such as aromatic esters, an alphatic diest
