A NEW SYNTHESIS OF α,β-UNSATURATED KETONES. ALLYLIC ALKYLATION OF 1-ISOCYANO-1-TOSYLALKENES
Moskal, Janusz,Leusen, Albert M. van
, p. 2585 - 2588 (2007/10/02)
Ketones (1) are homologated to enones 2 by alkylating (introduction of R3) the condensation products 4 (derived from 1 and tosylmethyl isocyanide), followed by acid catalyzed hydrolysis.
