The Diels-Alder reaction of substituted pyrano [3, 4-b]indol-3-ones with olefinic dienophiles is described. The role of the substitution pattern on the stability of the obtained 1, 2-dihydrocarbazoles is interpreted in terms of electronic and steric effects on the aromatization to the corresponding carbazoles.
描述了取代的吡喃并[3,4-b]吲哚-3-酮与烯属亲二烯物的Diels-Alder反应。取代模式对所获得的1,2-二氢咔唑的稳定性的作用是根据电子和位阻作用对相应咔唑的芳构化作用来解释的。
