Abstract

Isopinocampheylhaloborane-Methyl Sulfide as Hydroborating and Stereoselective Reducing Agent.-Among the haloboranes tested the iodo derivative is the most efficient, hydroborating alkenes and alkynes, e.g. (I) and (V), resp., with excellent regioselectivity. Stereoselective reductions are also achieved, cf. compound (VII), using the iodo derivative. -(CHA, J. S.; MIN, S. J.; KIM, J. M.; KWON, O. O.; KIM, E.
