In low temperature, reaction of ketone with sodium acetylide synthesized 1 - ethynyl - 2,3, 4,5 - tetramethyl - 2 - cyclopentene - 1 - ol; 1,2 - diphenyl - 2 - hydroxy - 3 - butine - 1 - one; 3,4 - diphenyl - 1,5 - hexadiine - 3,4 - diol and 3,4 - diphenyl - 3 - cyclopentene - 1 - one.
2-戊基环戊烯酮再与丙二酸二甲酯缩合,脱羧得到二氢茉莉酮酸甲酯.
Methyl dihydrojasmonate was synthesized from 2 pentyl 2 cyclopentanone and methyl malonate by condensation and decarboxylation.
4, 4- 二甲基 -2- 环戊烯 -1- 酮 ( DCO ) 由于其独特的结构, 因而应用广泛.
Bacause of the unique structure, 4,4 - dimethyl - 2 - cyclopenten - l - one ( DCO ) was extensively appliied to many fields.
