    摘要:
    An easy and high yielding transformation of epoxyketones and phenyl substituted epoxides to trans olefins in a convergent diastereoselective process is reported. The method was applied to the selective C-25 hydroxy-functionalisation of 3-keto-Delta(4)-cholestan-3-one, a key intermediate for the synthesis of C-25 hydroxy vitamin D-3.

    日期:1991.1
    Acid chlorides, complexed with excess aluminium chloride, reacted with ethene to form 3-methyl-2-buten-1-ones, i.e. rearranged di-addition products having a terminal isoprenoid skeleton, together with the usual β-chloropropanones. The latter were the sole products in the absence of excess catalyst. Acid chlorides containing a suitably situated π-system underwent intramolecular cyclization, e.g. 2-
