11-dioxocycloundecanecarboxylate (24), methyl 5-nitro-2,12-dioxocyclododecanecarboxylate (21), and 8-nitro-11-oxo-13-tridecanolide (7), which are intermediates, side products, or end products of the ‘Zip’ ring-enlargement reaction. The conformations of most of the medium-ring compounds are very similar to equal-sized ring compounds previously determine by other authors.
已经确定了反式-1-羟基-6-硝基-3-氧代双环[4.4.0]癸烷-2-羧酸甲酯(19),顺式-3-甲基-6-硝基-2-氧代双环[4.4 ]的晶体结构。 0]癸烷-1-醇(2),顺式-7-羟基-1-硝基双环[5.4.0] undecan-9-one(13)和中环化合物2-乙酰基-4-硝基环辛酮(9) ,5-硝基-2-氧代环辛烷甲酸甲酯(4),2-乙酰基-4-硝基环壬酮(11),2-乙酰基-4-硝基环癸酮(15),5-硝基-2,11-二氧环十一烷甲酸苄酯(24) ,5-硝基-2,12-二氧代环十二烷甲酸甲酯(21)和8-硝基-11-氧代-13-十三烷醇化物(7),它们是'Zip'环扩大反应的中间体,副产物或终产物。大多数中环化合物的构型与其他作者先前确定的等大小环化合物非常相似。
