Elaboration of the A ring of phomazarin by the Conrad-Limpach approach has been shown to be possible in the case of a protected hydroquinone substrate. However similar condensations using a suitably substituted naphthoquinone gave a lactam instead of the expected benzoquinolone. Attempts to annulate simplified models of the A-B rings with the appropriate diene have also been successful albeit in low
在保护的对苯二酚底物的情况下,通过康拉德-林帕赫(Conrad-Limpach)方法对苯丙扎林A环的修饰已被证明是可行的。然而,使用适当取代的萘醌的类似缩合反应产生内酰胺而不是预期的苯并喹诺酮。尝试用合适的二烯环化AB环简化模型的尝试也已成功,尽管收率低。
