The first example of glucose-containing Br?nsted acid synthesis and catalysis: Efficient synthesis of tetrahydrobenzo[α]xanthens and tetrahydrobenzo[α]acridines in water

Glucose sulfonic acid (GSA) was synthesized for the first time and used as an efficient catalyst for the preparation of tetrahydrobenzo[α]xanthens and tetrahydrobenzo[α]acridines via the reaction of aromatic aldehydes, 2-naphthol (or β-naphthylamine), and

Synthesis and Spectra of 12-(o- and p-R-phenyl)-9,9-dimethyl-7,8,9,10,11,12-hexahydro and 8,9,10,11-tetrahydrobenzacridin-11-ones. Structure Correction of 1,2,3,4,5,6-Hexahydro and 1,2,3,4-Tetrahydro-2,2-dimethyl-5-aryl-6-aza-9,10-benzophenanthren-4-on

It has been reported that the reaction of β-naphthylamine, dimedone and the appropriate aromatic aldehyde in ethanol gave 1,2,3,4,5,6-hexahydro-2,2-dimethyl-5-aryl-6-aza-9,10-benzophenanthren-4-ones, III, which upon treatment with chromic anhydride, yield
