nitriles through a one-pot, three-componentStreckerreaction of a carbonyl compound, amine, and acetone cyanohydrin in water has been developed. Reactions proceed very efficiently without any catalyst at room temperature with high chemoselectivity and give, in some cases, the expected α-amino nitrile pure after direct separation from water. The protocol is particularly efficient for both aliphatic and

The invention relates to novel products of formula (Ia) or (Ib):
these products being in all the isomeric forms and salts as drugs, notably as anticancer drugs.
We report herein a successful example of an aza-[2,3]-Wittig rearrangement in an allylic tertiary N,N-dibenzyl amine derived from (S)-alaninol or (S)-isoleucinol. This reaction occurs upon metalation at the benzylic position with a mixture of butyllithium/diisopropylamine/potassium t-butoxide and proceeds with a high 1,3 transfer of chirality.
