摘要

Abstract: 8, 16-Dialkyl-anti-5, 13-di-tert-butyl [2.2] metacyclophan-l-enes (13) and 2, 7-di-tert- butyl-trans-lOb, lOc-dialkyl-lob, 1 Oc-dihydropyrenes (2Oa-c) were prepared from the corresponding alkylbenzenes in several steps. The bromination of 13 and 20 with bromine in a carbon tetrachloride solution afforded 2, 7-di-tert-butyl-4, 5, 9, 1O-tetrabromo-trans-1 Ob, lOc-dialkyl-lOb, lOc-dihydropyrenes (2). Treatment of 20 with iodine in a boiling benzene ...
