the thiones 4a,b, the urea derivatives 5a,b, and N-acylated compounds 6a-e. Compounds 6b,d were ring-opened by hydrochloric acid in ethanol to yield trans-2-(1-carbethoxyethoxy)-1-acylaminomethylcyclohexane derivatives 7b,d. The 1H- and 13C-nmr investigation and X-ray analysis of 5b and 6c,d proved that the expected N-acylated derivatives were formed and that both rings of the trans anellated compounds
合成了反式-Perhydro-1,4-苯并恶唑啉-3-酮2a-c并将其转化为缩合骨架的过氢-反式-1,4-苯并x氮杂3a,b,硫酮4a,b,尿素衍生物5a,b,和N-酰化的化合物6a-e。用盐酸在乙醇中将化合物6b,d开环,得到反式-2-(1-乙氧基乙氧基)-1-酰基氨基甲基环己烷衍生物7b,d。对5b和6c,d的1 H和13 C-nmr研究和X射线分析证明了预期的形成N-酰化的衍生物,并且反式芳构化合物的两个环均具有椅子构象。
