This compound reacts with aldehydes and ketones cleanly to afford propargylic alcohols in excellent yields Unsubstituted propargylic alcohols are important synthetic intermediates in the synthesis of a number of natural products. In addition, the novel organoboron reagent of the present invention also demonstrates diastereomeric selectivity when reacted with enatiomerically pure aldehydes.

R 1 and R 2 are independently selected from the group consisting of a hydrogen atom, ester group, substituted silyl group, carboxyl group, cyano group, aliphatic C1-C20 hydrocarbon group, and phenyl group. The cis-olefin which is a useful intermediate for the synthesis of fine chemicals is selectively produced in high yields.

The method comprises the metal-catalyzed asymmetric 1,4-conjugate addition of vinylboron compounds to 2-substituted -4-oxy-cyclopent-2-en-1-ones. This method relies on the use of less toxic, easily-handled reagents, and can be performed under milder conditions than offered by some conventional methods, affording 2,3-disubstituted-4-oxy-cyclopentan-1-one compounds enantio- and diastereoselectively, which are precursors to the said prostaglandin and prostaglandin analogs, in high yield.
