A rhodium-catalyzed asymmetric hydroboration of enol carbamates yields α-boryl carbamates with a good enantioselectivity. The enol carbamate starting materials can be prepared with moderate Z-selectivity by using a modified Juila olefination; they can then be used as the resulting E/Z mixtures, taking advantage of the faster reactivity of the major Z-isomers in the directed hydroboration.
