A convenient synthesis of 3-arylbutanolides and 3-arylbutenolides
Gu, Jian-Xin,Holland, Herbert L.
, p. 3305 - 3315 (2007/10/03)
A series of 3-aryl-substituted butenolides and butanolides has been prepared in a common short synthetic sequence from the corresponding aryl aldehydes. The 3-arylbutanolides are prepared by cyclisation of 3-aryl-3- cyano-1-propanols, obtained by selectiv
