Cook, David C.,Lawson, Alexander

, p. 465 - 468 (2007/10/08)

2-Alkyl-Δ2-thiazolines react with 2-phenyl- Δ2-oxazojin-5-one to give 4-[1-(2-hippuroylamino-alkylthio) alkylidene]-2-phenyl-Δ2-oxazolin-5-ones and 4-[1-(2-hippuroylthio-alkylamino)alkylidene]-2-phenyl-Δ2- oxazolin-5-ones. 3-Phenylisoxazolin-5-one and 2-methylthio-1-azacycloalkanes react analogously to give 4-alkylidene compounds.
