A strategy for ketone synthesis with cyclopropanols as intermediates and its application to (+)-spirolaxine methyl ether is described. The synthesis also features an application of Fu's alkyl-alkyl Suzuki coupling.

[reaction: see text] The palladium-mediated ringopening of substitutedcyclopropanols has been found to take place predominantly at the less substituted C-C bond. Thus, sequential application of the titanium-mediated cyclopropanation of esters and the palladium-mediated ringopening of the resulting cyclopropanols provides a convenient method for functionalizing monosubstituted olefins.

Alkynylation of cyclopropanols with 1-bromo-1-alkynes has been devised for easy access to synthetically useful alk-4-yn-1-ones. This method broadens the utility of attractively functionalized cyclopropanols as a new class of homoenolate equivalent in C–C bond formation.
