The preparation and pentannulation reactions of 1-(phenylthio)-, 1-(methylthio)- and 1-(isopropylthio)cyclopropylphosphonium fluoborates are described.As part of a synthetic approach to portulal, a plant-growth regulator, 2-(carbomethoxy)-4-methylcyclohept-4-en-1-one is converted to its bicyclodecenone derivative.This annulation reaction illustrates the synthetic application and limitations of the 1-thio-substituted cyclopropylphosphonium reagents.
