Conversion of Saturated Ketones into 2-Lithiodienes via N,N-Bis-Tosylhydrazone Derivatives
Magnus, Philip,Roe, Michael B.
, p. 5479 - 5482 (1995)
Saturated N-tosylhydrazones can be converted into 2-lithiodienes via N,N-bis-tosylhydrazones and elimination to an α,β-unsaturated N-tosylhydrazone, followed by the Shapiro reaction.
