3-aminocyclohexene-2-one-1 is prepared by heating 5-oxohexanenitrile of the formula
and cyclohexane-1.3-diones and 3-alkoxycyclohexene-2- ones-1 are prepared by reacting a 3-aminocyclohexene-2- one-1 of the formula
wherein R represents amino or alkylamino, R3 represents a non-reactive substituent, and n is 0, 1 or 2, with water or a monohydric or dihydric alcohol of 1 to 10 carbon atoms.
The process provides the desired compounds, useful as intermediates in the preparation of medicines, agricultural chemicals, perfumes and resin substitutes, in good yields from readily available and inexpensive starting materials.
3-氨基环己烯-2-酮-1 是通过加热式 5-氧代己腈和环己烷-1.3-二酮以及 3-烷氧基环己烯-2-酮-1 而制备的。
和环己烷-1.3-二酮和 3-烷氧基环己烯-2-酮-1 是由式 3-氨基环己烯-2-酮-1 反应制备的。
其中 R 代表氨基或烷基氨基,R3 代表非反应性取代基,n 为 0、1 或 2,与水或 1 至 10 个碳原子的一元醇或二元醇反应。
该工艺提供了所需的化合物,可用作制备药物、农药、香水和树脂替代品的中间体,且起始原料容易获得,价格低廉,收率高。
