Abstract

Three analogues of 1a,25-dihydroxyvitamin D(3) (calcitriol), featuring a trans-fused decalin C,D-core with local S(2)-symmetry, and possessing identical side-chain and seco-B,A-ring structures, have been synthesized starting from readily available (4aR,8aS)-octahydronaphthalene-1,5-dione (7). The very short sequences involve the simultaneous introduction of the side-chain and seco-B,A-ring fragments via Suzuki and Sonogashira coupling reactions. The analogues are devoid of relevant biological activity.

摘要

已从容易获得的(4aR,8aS)-八氢萘-1,5-二酮(7)出发,合成了三种1α,25-二羟基维生素D(3)(骨化三醇)类似物,其具有具有局部S(2)-对称性的反式稠合十氢化萘C、D核,且具有相同的侧链和开环B、A环结构。非常简短的合成路线涉及通过铃木和宗和反应同时引入侧链和开环B、A环片段。这些类似物没有相关的生物活性。
