Origin of diastereoselectivity and catalytic efficiency on Isothiourea-mediated cyclization of carboxylic acid with alkenyl ketone
Computational and Theoretical Chemistry(2020)
摘要
•Origin of diastereoselectivity on the isothiourea-catalyzed reaction was explored.•AIM analysis indicates that hydrogen bonds are responsible for the stereoselectivity.•Efficiency of isothioureas was predicted by computing nucleophilic atom energy Ea-.
