SYNTHESIS OF 3-ALKYLCYCLOPENTANE-1,2-DIONES BY ACID-CATALYSED REARRANGEMENTS OF α-KETOGLYCOL DERIVATIVES
Pattenden, Gerald,Teague, Simon
, p. 1403 - 1404 (2007/10/02)
Treatment of the adducts (3) derived from 1,2-bis(trimethylsilyloxy)cyclopentene and acetals, with p-toluene sulphonic acid in hot benzene is shown to lead to the corresponding 3-alkylcyclopentane-1,2-diones (4).
