Chirality Control of Tropos Diphenylmethane-Derived Phosphoramidites by Chiral Dienes: Its Application to Asymmetric Michael Addition
摘要:
The Rh complex of tropos diphenylmethane-derived phosphoramidite could be chirally controlled to adopt single chiral conformation upon addition of a chiral diene. In the asymmetric Michael addition of alpha-cyanocarboxylates catalyzed by the Rh complexes, the chiral diene and bisphenylmethane-derived phosphoramidite functioned to attain higher enantioselectivity and catalytic activity via asymmetric activation.
