Gif-type reactions have been used to perform direct oxidative functionalization of the title compound (HCTD, 1). Thus, GoAggIII and GoAggIV promoted oxidations of 1 afford 1-(2′-pyridyl)heptacyclo[6.6.0.02,6.03,13.04,11.05,9-.010,14]tetradecane [i. e., 1-(2′-pyridyl)HCTD, 2] in 6–10% isolated yield. In addition to 2, GoAggV promoted oxidation of 1 produced heptacyclo[6.6.0.02,6.03,13.04,11.05,9.010
Gif型反应已用于进行标题化合物(HCTD,1)的直接氧化功能化。因此,GoAgg III和GoAgg IV促进了1的氧化,从而提供了1-(2'-吡啶基)七环[6.6.0.0 2,6 .0 3,13 .0 4,11 .0 5,9- .0 10,14 ]十四烷[即1-(2'-吡啶基)HCTD,2 ],分离产率为6-10%。除2外,GoAgg V促进了1个产生的七环的氧化[6.6.0.0 2,6 .0 3,13 .0 4,11 .05,9 .0 10,14 ]十四烷-7-一(HCTD-7-one; 3)和1-(4'-吡啶基)HCTD(4),分离产率低。最后,通过使用Fe II - t- BuOOH系统进行的1氧化,得到几种产物,包括六环[6.6.0,0 2,6 .0 3,13 .0 4,11 .0 5,9 ]十四烷-10 ,14-二酮(6)和14-羟基六环[6.6.0,0 2,6 .0 3,13
