  • A convenient and highly stereoselective synthesis of 4α-deuterio and -Tritio steroids catalyzed by Pd
    作者:Michael H. Rabinowitz
    DOI:10.1016/0040-4039(91)80758-x
    日期:1991.10
    A simple and highly stereoselective synthesis of [4α-2H]- and [4α-3H]-Δ5-3β-hydroxysteroids is presented. Palladium(0)-mediated borodeuteride reduction of readily-available cholest-5-en-3β,4β-diol cyclic carbonate provides [4α-2H]- Δ5-and Δ4-cholesterol in a 12:1 ratio. Reduction of [4α-3H]-cholest-5-ene-3β,4β-diol cyclic carbonate with NaB1 H4 and Pd(0) resulted in [4β-3H]-cholesterol.

    have investigated the behaviour of sulfonic peracids 2in situ generated towards olefins 7a,7b,9,11,14,16,18, allylic and homoallylic alcohols 20,22,24,26,28,30,33 and α,β-unsaturated ketones 35,37,39. Generally, the epoxidation proceeds in a peracid-like manner with greater diastereoselectivity than those by common oxidants. In particular, the epoxidation of Δ4 3-ketosteroids 39a-i led to 4α,5α-epoxides
