摘要：

A set of selected bimolecular reactions leading to asymmetric and dissymmetric products was carried out in cholesteric solvents with the aim of obtaining asymmetric syntheses. In all cases, the products did not show significant optical rotation. The reasons for the lack of asymmetric induction are briefly discussed.
