Abstract: Three analogues of 1a,25-dihydroxyvitamin D3 (calcitriol), featuring a trans-fused decalin C,D-core with local S2-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.
Keywords: Suzuki coupling; Sonogashira reaction; Calcitriol analogues
