Application

Cyclohexene has been used in the green synthesis of cyclohexene oxide via hydrogen peroxide epoxidation in glycerol-based solvents using bis[3,5-bis(trifluoromethyl)-diphenyl] diselenide as a precatalyst. It can also undergo hydrogen peroxide oxidation in the presence of peroxytungstate-oxalic acid complex catalyst to form adipic acid.

In the absence of any additional catalysts, the reactions of (CF(3)SO)(2)CH(2), aldehydes, and 1,3-dienes gave gem-bis(triflyl)cyclohexenes in excellent yields with high regioselectivity. gem-Bis(triflyl)cyclohexene products can be easily converted to the corresponding aryl trifluoromethyl sulfones.

The asymmetric synthesis of novel cyclohexene nucleoside analogues 12 and 15 is described. An enantiospecific Diels-Alder reaction between (E,E)-diene 2 and (+)-5-(d-mentyloxy)-2(5H)-furanone 3 provided the cycloadduct isomer 4. Three additional steps yielded amine 8 allowing the constructions of the thymine
