The synthesis of both mono and bisbenzannulated spiroketals using an oxidative radical cyclization approach is investigated. Although unsuccessful in uncovering a novel route toward bisbenzannulated spiroketals, the oxidative radical cyclization does facilitate a new approach to monobenzannulated spiroketals such as those found in berkelic acid and in the chaetoquadrins.
研究采用氧化自由基环化方法合成单苯并annulated螺酮和双苯并annulated螺酮。虽然未能成功发现双苯并环化
螺环酮的新路线,但氧化自由基环化法确实为单苯并环化
螺环酮的合成提供了一种新方法,例如在贝可酸和混沌素中发现的单苯并环化
螺环酮。
