7,8,9,10-Tetrahydro-6,6,9-trimethyldibenzo[b,d]pyran and 5,6,7,8,9,10-hexahydro-6,6,9-trimethylphenanthridine have been prepared by reaction of pulegone with lithium ortho-lithium phenolate and lithium ortho-lithium N-trimethylsilylaniline. The cyclization into the annellated systems could be performed under essentially non-acidic conditions.
通过反应制备了7,8,9,10-四氢-6,6,9-三甲基二苯并[ b,d ]吡喃和5,6,7,8,9,10-六氢-6,6,9-三甲基菲啶与锂长叶薄荷酮邻-锂酚盐和锂邻锂ñ -trimethylsilylaniline。可以在基本上非酸性的条件下进行环化到环化系统中。
