A transition metal-free deuteride reduction protocol of N-tert-butanesulfinyl ketimines with B2pin2 has been developed. After screening of reaction parameters, such as base, solvent, and the amount of B2pin2, a series of deuterated secondary amines were obtained in reasonable yields with excellent deuterium purity by using D2O as the deuterium source. Mild reaction conditions, operational simplicity, and easily scaled up to gram scale are the considerable advantages of this methodology. After deprotection of tert-butanesulfinyl, cyclopentan-1-d-amine is obtained in high yield.

Key words: deuteride reduction, N-tert-butanesulfinyl ketimines, bis(pinacolate)diboron, deuterated secondary amines
