Diastereoselectivity in the epoxidation of substituted cyclohexenes by dimethyldioxirane

Three series of compounds based on the cyclohexene framework have been epoxidized by dimetbyldioxirane. A pronounced dependence of epoxide diastereoselectivity on substituent has been observed. In addition there is a solvent influence on this stereoselectivity. The results have been explained by invoking steric, H-bonding, and dipole - dipole influences on the epoxide stereochemistry.

Syn Bromination of 2-Cyclohexen-1-ol Benzoates. Isolation of a trans-3-Bromocyclohexano-cis-1,2-(2'-anisyl-1',3'-dioxolan-2'-ylium) Intermediate

The addition of molecular bromine to 2-cyclohexen-1-ol benzoate, p-methylbenzoate, and p-methoxybenzoate in aprotic solvents of low to moderate dielectric constant gave, besides the expected vicinal trans diaxial and diequatorial dibromides, large amounts
