The diastereoselectivities and rates of epoxidation (upon treatment with Cl3CCO2H then m-CPBA) of a range of cis- and trans-4-aminocycloalk-2-en-1-ol derivatives (containing five-, six-, and seven-membered rings) have been investigated. In all cases

A highly diastereoselective cyclopropanation protocol has been employed in the syntheses of trans-SCH-A and cis-SCH-A. This strategy encompasses a stereodivergent procedure for the preparation of syn- and anti-cyclopropane diastereoisomers in high dr

A highly chemo- and diastereoselective protocol for the cyclopropanation of tertiary allylic amines with Shi's carbenoid [CF 3CO 2ZnCH 2I] is described. The high levels of diastereoselectivity observed in these reactions may be attributed to chelatio
