Benzyl ethers were prepared from alcohols by reaction with chloro(phenylmethylene)dimethylammonium chloride and sodium hydrogen telluride in sequence. The salt (1)[Me2NC(R1)OR2Cl–; R1= H, R2= cholest-5-en-3β-yl] and sodium borohydride gave the borane complex of 3β-dimethylaminomethoxycholest-5-ene. Salt (1; R1= Ph, R2= cholest-5-en-3β-yl or 5α-cholestan-3β-yl) and ammonia or hydrazine gave the steroidal
通过依次与氯(苯基亚甲基)二甲基氯化铵和碲化氢钠反应,由醇制得苄基醚。盐(1)[我2 NC(R 1)OR 2氯- ; R 1= H,R 2=胆甾-5-烯-3β-基],硼氢化钠得到3β-二甲基氨基甲氧基胆甾-5-烯的硼烷配合物。盐(1; R 1 = Ph,R 2 =胆甾-5-en-3β-基或5α-胆甾-3β-基)和氨或肼得到甾族苯甲酸酯或苯甲酰肼酸盐。
