FACILE SYNTHESIS OF 2-SUBSTITUTED CYCLOPENTENONES
Baldwin, S. W.,Blomquist, H. R.
, p. 3883 - 3886 (1982)
An efficient synthesis of 2-substituted cyclopentenones is reported.Key reactions are the cyclopropanation of 2,2-dimethyl-3(2H)-furanone and subsequent conversion to the title compounds by oxidative fragmentation.
