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.
