A simple application of the highly efficient semi-two-phase monohydrolysis
of meso diesters is described. Using this reaction, symmetric dialkyl 5,6-e
poxybicyclo[2.2.1]hept-2-ene-2,3-dicarboxylates yield 6-formyl-1-alkoxycarb
onylbicyclo[3.1.0]hex-2-ene-2-carboxylic acids in a racemic manner in high
yields in only two steps, providing additional support for the mechanisms o
f the semi-two-phase monohydrolysis and the rearrangement. (C) 2000 Elsevie
