—The reaction of 2-amino-1,4-naphthoquinones with ninhydrin at 50–60°C in acetic acid leads to 4b,11b-dihydroxy-4b,5-dihydrobenzo[f]indeno[1,2-b]indole-6,11,12(11bH)-triones. The products were isolated as hydrates, and, when heated in DMSO with methanesulfonic acid or in acetic acid in the presence of sulfuric acid, they converted into 13-R-benzo[f]isochromeno[4,3-b]indole-5,7,12(13H)-triones. The
-2-氨基-1,4-萘醌与茚三酮在50–60°C的乙酸中反应,生成4b,11b-二羟基-4b,5-二氢苯并[ f ]茚并[1,2- b ]吲哚- 6,11,12(11 BH)-triones。分离出水合物形式的产物,当在DMSO中与甲磺酸或在乙酸中,在硫酸存在下加热时,将其转化为13-R-苯并[ f ]异色素[4,3 - b ]吲哚-5,7,12 (13 H)-三酮。4b的转换,11B二羟基4B,5-二氢苯并[率˚F ]茚并[1,2- b ]吲哚6,11,12(11 BH)-triones至13-R -苯并[ ˚F ] isochromeno [4,3- b ]吲哚-5,7,12(13硫酸在乙酸中的溶液中的H)-三酮与哈米特酸度函数呈线性关系。
