The separate, and combined, influences of ether, silyl ether and cyclic ketal groups at positions 3 and 5 on the mode and efficiency of 6-heptenoyl radical cyclizations have been studied with a view to the eventual synthesis of 1α,25-dihydroxyvitamin D3.
为了最终合成1α,25-二羟基维生素D 3,研究了3位和5位的醚,甲硅烷基醚和环状缩酮基对6庚烯基自由基环化的方式和效率的单独影响和综合影响。。
