(E)-, (Z)-Interconversion in 3-aroylmethyl-5-arylmethylene-2,4-dioxo-1,3-thiazolidines
摘要:
The (E)-, (Z)-interconversion in 3-aroylmethyl-5-arylmethylene-2,4-dioxo-1,3-thiazolidines is simply achieved upon treating with phenylhydrazine in acetic acid solutions. Configurational assignments are based on H-1-NMR spectral data.
