“…In continuation of earlier research work [16][17][18][19], we report here in a simple, rapid, efficient and environmentally benign solvent-free iodination of 2-acetyl-1-naphthol using iodine and iodic acid in combination with grinding at room temperature. The iodination occur selectively at electron rich centre i.e.…”

“…Pyrazoline is also synthesized by using microwave irradiation [10], tungsten light irradiation [11], and ultrasound irradiation [12]. Recently, various modified methods have been reported for synthesis of 2-pyrazolines by using different catalysts such as KHSO 4 [13][14][15][16][17][18][19].…”

“…Thus, a green and efficient protocol for the synthesis of 3,5-disubstituted 2-pyrazolines was achieved by the reaction of chalcones with hydrazine hydrate under irradiation with tungsten light. The reaction occurs with no need of catalyst and in a short reaction time giving quantitative yields of the 2-pyrazolines (Scheme 32) [315]. [316].…”

Chalcones belong to the flavonoid family which constitutes one of the major classes of naturally occurring oxygen heterocyclic compounds. The ,-unsaturated carbonyl system of chalcones possesses two electrophilic reactive centers allowing them to participate in addition reactions via attack to the carbonyl group (1,2-addition) or involving the-carbon (1,4-conjugate addition), leading to the synthesis of promising bioactive heterocyclic compounds. The purpose of this review is to present a systematic survey of the most recent literature that uses chalcones in the synthesis of biologically active 5-and 6-membered nitrogen heterocycles such as pyrroles, indoles, isoxazoles, imidazoles, pyrazoles, indazoles, triazoles, tetrazoles, pyridines and pyrimidines. Efficiency, easy-to-handle and cheap reagents, alternative heating conditions and greener protocols will be highlighted. In this review we will cover the literature since the beginning of the 21 st century in more than 400 publications.
