12-dibromopentacyclo[5.5.0.02,6.03,10.05,9]dodec-11-ene (12). Reaction of 8a with Br2 under a variety of experimental conditions led to the isolation and characterization of 11,11,12-tribromopentacyclo[5.5.0.02,6.03,10.05,9]dodecane (7), 12, and 2,exo-3,exo-12-tribromopentacyclo[7.3.0.02,7.04,11.06,10]dodecane (13). Similarly, reaction of 8b with Br2 under a variety of experimental conditions led to
将五环[5.5.0.0 2,6 .0 3,10 .0 5,9 ] dodecan-11-one(4)转换为11-Br和11-Cl取代的五环[5.5.0.0 2,6 .0 3的步骤,10 0.0 5,9- ]十二碳-11 -烯(即,图8A和图8B,分别地)进行了描述。此外,将笼型酮4转化为相应的α,α'-二溴衍生物10,随后使其与H 2 N-NH 2和甲醇性CuBr 2 -NEt 3顺序反应,从而得到11,12-二溴五环[5.5] .0.0 2,6.0 3,10 .0 5,9 ] dodec-11-ene(12)。在多种实验条件下8a与Br 2的反应导致分离并表征了11,11,12-三溴五环[5.5.0.0 2,6 .0 3,10 .0 5,9 ]十二烷(7),12和2,exo -3,exo -12-tribromopentacyclo [7.3.0.0 2,7 .0 4,11 .0 6,10
