formamide 7. Similarly, photolysis of trans-xylopinine N-oxide (12) supplies lactam 14 and amide 15. Oxaziridine 4 is a probable intermediate in these transformations, so that selective oxidation of the berbine nucleus at C-6 has been achieved, accompanied by fission of the N-7-C-14 bond. LAH reduction of lactam 5 gives rise to dibenzazecine 8, while similar treatment of amide 7 generates dibenzazonine 10
反式卡那汀N-氧化物的光解作用(3)导致内酰胺5和甲酰胺7。类似地,反式-草嘌呤N-氧化物的光解作用(12)可提供内酰胺14和酰胺15。恶唑烷4是这些转化中可能的中间体,因此已经实现了C-6处的贝宾核的选择性氧化,并伴随着N-7-C-14键的裂变。内酰胺5的LAH还原会产生dibenzazecine 8,而类似的酰胺7处理会生成dibenzazonine 10。或者,酸水解7提供了二苯甲zon嗪11。
