B. Wladislaw et al., NOVEL REACTION - DECARBOXYLATIVE RAMBERG-BACKLUND REARRANGEMENT IN SOME ALPHA-ISOPROPYL SULFONYL CARBOXYLIC ESTERS, Tetrahedron letters, 36(46), 1995, pp. 8367-8370
The reaction of some isopropylsulfonyl alpha-mono and disubstituted es
ters with KOH/t-BuOH/CCl4 is reported. For the alpha,alpha-dialkyl and
alpha-monoaryl substituted derivatives the key step of this reaction
is proposed to be the decarboxylative 1,3-displacement in the chlorina
ted intermediates.
