NettetA one-step synthesis of 1-indanones 22 through the NbCl 5 -induced Friedel–Crafts reaction, has been described by Barbosa et al. in 2015 [20]. The reaction was carried out using 3,3-dimethylacrylic acid ( 19 ), aromatic substrate 20 and highly oxophilic NbCl 5 … NettetIn this paper we report the synthesis of a new series of benzenesulfonamides and the evaluation of their binding properties on ETAh and ETBh receptor subtypes. Some new derivatives behave as selective ETAh receptor ligands and among them, 2-{[(4-chloro-3-methyl-5-isoxazolyl)amino]sulfonyl}-N-(2,4,6- trimethylphenyl)benzamide (23) was the … siam park tenerife age restrictions
