Hexahydro-pentalene and -indene nitroalcohols are obtained by reaction of 3-(4-morpholinyl)-3-buten-2-one with cyclic nitroolefins. With 1-nitro-cyclohexene a [4 + 2] heterocyclization intermediate Is separated, while an unusual product of double addition is obtained from the hexahydro-pentalene derivative in aqueous acidic medium.
通过使3-(4-吗啉基)-3-丁烯-2-酮与环状硝基烯烃反应获得六氢戊烯和-茚烯硝基醇。用1-硝基-环己烯分离出[4 + 2]杂环中间体,而在含水酸性介质中从六氢戊烯衍生物中获得了不寻常的重复加成产物。
