Tamarind Juice Assisted Benign Synthesis Of 2,3-Dihydro-1h-Perimidine Derivatives

A green and efficient way to make 2,3-dihydro-1H-perimidine derivatives is through a one pot reaction of 1,8-diaminonaphthalene with different aromatic aldehydes using tamarind (Tamarindus indica L.) juice. The reactions were carried out in mild conditions, giving us the desired products in good or excellent yields with short reaction times. Tamarind juice was inexpensive, and easily available, and it was a metal-free and eco-friendly catalyst. The protocol is easy to follow, easy to separate products, low amount of catalyst, and does not include hazardous chemicals and chromatographic purification. This green way shows that tamarind juice is a good green catalyst for biologically important perimidine derivatives.

Solanum Xanthocarpum Assisted Benign Synthesis of Benzimidazole

Heterocyclic chemistry is major and fascinating branch of chemistry where you have scope to synthesize molecules which will show variety of pharmacological activities. Numerous compounds of heterocyclic molecules were synthesized by researchers and tested for activities and utilised in health care industry to serve the peoples. Among these heterocyclic molecules we in this paper reporting synthesis of benzimidazole using novel catalyst. Catalyst employed here is Solanum Xanthocarpum which show exciting results for benzimidazole synthesis. Synthesis show good yield of product without utilising harmful catalyst. Products obtained were established on the basis of standard methods. Method used is benign for environment which applies green chemistry for heterocyclic synthesis.
