Bifunctional chiral phosphane

Figure 2.8 Sterically congested bifunctional chiral phosphane-amides for use as catalysts.

SCHEME 11.43. Chiral bifunctional thiourea-phosphane-catalyzed allylic amination of MBH acetates and carbonates with phthalimide. 

In the same area, these authors have also investigated the efficiency of various chiral sterically congested phosphane-amide bifunctional organocatalysts with a binaphthyl scaffold in asymmetric aza-Morita-Baylis-Hillman reactions of A -sulfonated imines with activated olefins such as methyl and ethyl vinyl ketones." The corresponding aza-Morita-Baylis-Hillman adducts could be obtained in moderate to excellent yields (37-98%) and moderate to good...
