Intramolecular heterocyclization of thiosemicarbazones derived from α,β-enones under acid activation of one nucleophilic center afforded previously unknown 2-(2-arylethenyl)-2,3-dihydro-1,3,4-thiadiazoles. The transformation involves the thiol tautomer of thiosemicarbazone without participation of the conjugated carbon-carbon double bond.
在一个亲核中心的酸活化下,由α,β-烯酮衍生的硫代半咔唑的分子内杂环化提供了以前未知的2-(2-芳基乙烯基)-2,3-二氢-1,3,4-噻二唑。该转化涉及硫半脲的巯基互变异构体,而没有共轭碳-碳双键的参与。
