the addition of some aryl- and alkyllithium derivatives to some hindered and/or enolisable ketones in different solvents (polar and apolar) and, in some cases, at different temperatures and reaction times, will be presented here. The reversibility of the addition of aryllithium to these specific ketones will be observed and discussed. This approach is then used to prepare new steroids as precursor for
本文将介绍在不同溶剂(极性和非极性)中,在某些情况下,在不同的温度和反应时间下,将某些芳基和烷基锂衍生物添加到某些受阻和/或可烯化的酮中的研究。将观察和讨论向这些特定的酮中添加芳基锂的可逆性。然后,该方法用于制备新的类固醇作为潜在有趣的取代睾丸激素的前体。
