A series of (R,S)‐1‐{[5‐(substituted)sulfanyl‐4‐substituted‐4H‐1,2,4‐triazole‐3‐yl]methyl}‐1,8‐diethyl‐1,3,4,9‐tetrahydropyrano[3,4‐b]indoles (5a–v) were designed and synthesized using a five‐step synthetic protocol that involves substituted benzyl chlorides and (R,S)‐5‐[(1,8‐diethyl‐1,3,4,9‐tetrahydropyrano[3,4‐b]indole‐1‐yl)methyl]‐4‐substituted‐2,4‐dihydro‐3H‐1,2,4‐triazole‐3‐thiones in the final...
A group of 3,5‐diaryl‐2‐pyrazoline and hydrazone derivatives was prepared via the reaction of various chalcones with hydrazide compounds in ethanol. Twenty original compounds were synthesized. Ten of these original compounds have a pyrazoline structure, nine of these original compounds have a hydrazone structure, and one of these original compounds has a chalcone structure. Structural elucidation...
