✦ Synopsis
1,3,5‐Triphenyl‐5‐(4‐phenyl‐2‐piperidinothiazol‐5‐yl)penta‐2, 4‐dien‐1‐one. – An Example of the Fixation of N‐Invertomers by Different Crystal Structures
From an ethanol/acetone solution of 1,3,5‐triphenyl‐5‐(4‐phenyl‐2‐piperidinothiazol‐5‐yl)penta‐2,4‐dien‐1‐one 3 (Ar = Ar′ = Ar″ = Ph, NR~2~ = piperidino) yellow‐orange and red crystals are obtained simultaneously. X‐ray structure determinations show that the N‐invertomers of the dienone, easily convertible in solution, are fixed in the solid state by different crystal structures. magnified image
