Abstract

Photoisomerization of encapsulated Z-enecarbamates within the hydrophobic chiral cavities of gamma-CD showed higher diastereoselectivities in the photoproducts than those obtained in solution. The selective encapsulation of the enecarbamates and the following isomerization process are both diastereoselectively controlled by gamma-CD.

摘要

γ-环糊精疏水手性腔内包封的Z-烯氨基甲酸酯的光异构化在光产物中表现出比在溶液中更高的非对映选择性。烯氨基甲酸酯的选择性包封和随后的异构化过程均受γ-环糊精的非对映选择性控制。
