cis- and trans-2-Hydroxymethylcyclohexanol were cyclized with ethyl chloroacetate or ethyl 2-chloropropionate in the presence of sodium hydride to synthesize stereoisomeric perhydro-4,l-benzoxazepin-2-ones (4-9). The relative configurations and predominant conformation of the compounds prepared were confirmed by 4H and 13 NMR spectroscopy.
在氢化钠存在下,用氯乙酸乙酯或2-氯丙酸乙酯使顺式和反式-2-羟甲基环己醇环化,合成立体异构的过氢-4,1-苯并恶唑啉-2-酮(4-9)。通过4 H和13 NMR光谱证实了所制备化合物的相对构型和主要构象。
