The two-component nature of the Staudinger reaction suggests that double asymmetric induction may afford improved diastereoselectivity. The chiral groups may be paired in any of three ways (1) a chiral aldehyde with a chiral amine to place two defined stereocenters on the imine, (2) an imine with a chiral A -substituent with a chiral ketene substituent, and (3) an imine with a chiral C-substituent with a chiral ketene. Some examples of these possibilities have been reported. [Pg.56]

Scheme 16.12 Three-component Staudinger-type reaction with ji-glycosyl azide 4 stereose-lectively leads to the ji-glycosyl amides 48. a-Clycosyl amides can only be obtained from a-glycosyl azide 49 with strong acylating agents to prevent complete anomerization of the Intermediate lmlnophosphorane °...
