The trans-1-anilino-2-aminoindane derivative 2a derived from
the adduct 1 of indene and N,N-dichlorourethane is
suitably functionalised for further elaboration to give novel fused ring
systems. This report describes the use of 2a to provide access to the
benz[ f ]indeno[1,7-bc]
azepines 4a,b and the
benz[e]indeno[2,1-b][1,4]diazepines 5a,b. Further
elaboration of 4a affords a route to the
diazabenzo[5,6]cyclohepta[def]fluorene 9.

生物 2a 经过适当的官能化处理,可进一步制备出新型的融合环系统。本报告介绍了利用 2a 制备
苯并[f]茚并[1,7-bc]氮杂卓 4a,b 和苯并[e]
茚并[2,1-b][1,4]二氮杂卓 5a,b。进一步阐述 4a 后,就可以得到重氮并[5,6]
环庚烷并[def]
