The reaction of acetonecyanohydrin with MeLi affords a LiCN·acetone complex that can be made to react with epoxides in THF, either in one-pot or using isolated samples of the cyanide complex, to cleanly afford β-hydroxy nitriles upon aqueous workup; in situ hydride reduction of nitriles affords 1,3-amino alcohols.

Functionalized epoxides are easily and efficiently converted to β-hydroxy nitriles in good yield with high regio- and stereoselectivity upon treatment with lithium cyanide in refluxing anhydrous THF. The conditions described permit a one-pot conversion of epoxide to 1,3-amino alcohol via hydride reduction of the nitrile.
