phenanthro[10,9-b]oxepine 11C, or benz[3,4]anthra[1,2-b]oxepine 11D isomers respectively. The total racemization of arene oxide 5ARS and formation of oxepine 11A from the bromoMTPA precursor 8ARRS* are in accord with earlier PMO predictions based on resonance energy considerations. Photoisomerization of arene oxides 5ARS/5ASR, 5CRS/5CSR, and 5DRS/5DSR was found to yield the corresponding oxepines 11A, 11C,
由对映纯的二溴MTPA前体9A RRS *合成的Dibenz [ a,h ]蒽3,4-氧化物5A RS被发现已完全消旋,并伴随有苯并[5,6]蒽[1,2- b ]奥沙平 11A。菲3,4-氧化物5B RS,从对映纯细菌中获得代谢物 观察到,通过涉及氯醇酯16B的改进的合成方法,顺式-3,4-二羟基-3,4-二氢菲12B在环境温度下自发消旋。Dibenz [ a,h ]蒽3,4-氧化物5A RS / 5A SR,菲3,4-氧化物5B RS / 5B SR,联苯1,2-氧化物5C RS / 5C SR和dibenz [ a,c ]蒽1,2-氧化物5D RS / 5D SR通过新方法从相应的外消旋顺式-四氢二醇前体14A - 14D获得的,没有任何证据表明形成了苯并[5,6]蒽[1,2- b ]奥沙平 11A,萘[1,2- b ]奥西平 11B,菲咯[10,9- b ]奥沙平 分别为11C或苯并[3
