概要
- 論文の詳細を見る
3-(Diethylamino)crotonic acid esters and 1-diethylamino-1-cyclohexene react with <I>N</I>-(phenylsulfonyl)benzohydrazonoyl chloride to give substituted pyrazoles in 87–89% and 1.4% yields, respectively, the corresponding morpholine enamines affording no pyrazoles. The pyrazole formation is interpreted in terms of a step-by-step process involving the nucleophilic attack of the enamines on the hydrazonoyl chloride.
