Probing for steric and electronic effects in diastereoselective dioxirane epoxidations compared to the oxygen transfer by peroxy acids

The spiro transition state for the oxygen transfer by dioxiranes is substantiated by the fact that no enhanced steric effects are observed when dioxiranes with alkyl groups of different size are employed, as manifested by the same (within the experimental error) diastereoselectivities in the epoxidation of 2-menthene and 1,3-dimethylcyclohexene for different dioxiranes. The π-facial selectivity (anti attack) in the epoxidation of the acetate and the methyl and trimethylsilyl ether derivatives of 2-cyclohexenol derives from steric interactions, whereas a pronounced electronic effect (electrostatic repulsion) is held responsible for the high anti selectivity of peroxides such as ascaridol and 3-hydroperoxycyclohexene. Quite generally, dioxiranes display only slightly higher diastereoselectivities than mCPBA in sterically controlled epoxidations of cycloalkenes. VCH Verlagsgesellschaft mbH, 1997.

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.

Solvent Tuning of Diastereoselectivity in Dimethyldioxirane Epoxidation Reactions

Diastereoselectivity in the epoxidation of cyclohex-2-en-1-ol shows a remarkable solvent dependence.In some solvent systems the substrate OH group apparently can provide a cis selectivity through H-bonding.

SYNTHESIS OF BOTH ENANTIOMERS OF ERYTHRO-6-ACETOXY-5-HEXADECANOLIDE, THE MAJOR COMPONENT OF A MOSQUITO OVIPOSITION ATTRACTANT PHEROMONE

Stereoselective synthesis of both (5S,6R)-(+)- and (5R,6S)-(-)-6-acetoxy-5-hexadecanolides, the major component of a mosquito oviposition attractant pheromone, was achieved from (S)-2-cyclohexen-1-ol.
