A new one-pot method for the synthesis of α-siloxyamides from aldehydes or ketones and its application to the synthesis of (-)-bestatin

(equation presented) A new one-pot method for the synthesis of α-siloxyamides is described. The three substrates, H-C(CN)2O-SiMe2t-Bu, aldehydes or ketones, and primary or secondary amines, are simply mixed in one portion in acetonitrile or ether; the α-siloxyamides are obtained within short peroids in excellent yields in many cases. As a demonstration of our method, the synthesis of (-)-bestatin was carried out.

A STEREOCONTROLLED SYNTHESIS OF (-)-BESTATIN FROM AN ACYCLIC ALLYLAMINE BY IODOCYCLOCARBAMATION

1,2-Asymmetric induction of iodocyclocarbamation is described by using allylamines 2 and 6 and the method has been succesfully applied to a stereocontrolled synthesis of bestatin.
