The first example of glucose-containing Brønsted acid synthesis and catalysis: efficient synthesis of tetrahydrobenzo[α]xanthens and tetrahydrobenzo[α]acridines in water
摘要:
Glucose sulfonic acid (GSA) was synthesized for the first time and used as an efficient catalyst for the preparation of tetrahydrobenzo[alpha]xanthens and tetrahydrobenzo[alpha]acridines via the reaction of aromatic aldehydes, 2-naphthol (or beta-naphthylamine), and dimedone in water. Up to four new bonds and one new ring were formed in one-pot with water as the only by-product in these two reactions. The work opens up a new and efficient synthesis and application of sugar-containing Bronsted acid. (C) 2013 Elsevier Ltd. All rights reserved.
