| 1 | A novel solid state Michael addition reaction of N-heterocyclic compounds containing active C-H bond显示文摘In this paper,a novel solid state Michael-type addition reaction of N-heterocyclic compounds containing the active-CH group was investigated.3-Methyl-l-phenyl-5-pyrazolone (MPP) and indole (In) reacted with 4-arylmethylene-3-methyl-l-phenyl-5-pyrazolone (1) hi the solid state at room temperature to give the corresponding adducts,aryl-4,4’-bis(5-hydroxy-3-methyl-l-phenyl-pyrazolyl) methane (2a-n) and l-aryl-l-(5’-hydroxy-3’-methyl-1’-phenyl-4’-pyrazolyl)-l-(3'-indolyl) methane (3a-n),respectively.This is a feasible method for preparing the compound which contains two heterocyclic groups on the same carbon. | Li, XL Wang, YM Tian, B Meng, JB | 1996 | Chinese Journal of Chemistry1996，14，5： | 3 |
