摘要：

The alkyl carbonate esters of cholesterol have a helical twisting power P which saturates quickly with chain length, in accord with a model attributing this twist to the effective length of the alkyl chain along the nearest C-O bond. However, compounds having a very small P, such as cholesteryl 2-(2-ethoxyethoxy)ethyl carbonate, appear to change chirality according to the environment. Dicholesteryl compounds have anomalously large P, suggesting a more complex interaction such as structural disarray or bridging of helicoidal arrays.
