Impairment of conditioned avoidance response in Fyn-kinase deficient mice;
Fyn-激酶缺损小鼠的条件性回避反应能力低下(英文)
Some useful and controllable reaction results were obtained through such investigation, in which, 16R-bromopregnane-3S,20S-diol diacetate was chemo-selec-tively converted into pregn-16-ene-3S,20S-diol diacetate, 16R-bromopregnane-3S,20S-diol, preg-nane-3S,16S,20S-triol, pregne-14,16-dien-3S-ol acetate and androst-16-en-3S-ol respectively.
这些条件可控性反应结果不仅为甾体药物和生物活性天然甾体化合物合成提供了新的合成中间体,也为它们新合成策略和途径的设计提供了机遇。
