The steric effects of allylic substituents in the epoxidations bonding is ineffective and steric interactions cause a higher trans selectivity. The conformationally fixed cis-and trans-with methyltrioxorhenium/urea/hydrogen peroxide adduct (MTO/UHP) have been assessed for a series of 3-alkyl-5-tert-
