SYNTHESES OF NOVEL DIBENZO[d,f]HETERONINS INCORPORATING GROUP 15 AND 16 HEAVIER ELEMENTS

[摘要]：Fully unsaturated dibenzo[d,f]heteronins incorporating Group 15 (P, As, Sb) and Group 16 (S, Se, Te) heavier elements have been prepared via a common 1,8-dilithium intermediate. These heteronins, except for dibenzothionin, are the first examples of fused nine-membered heterocyclic ring. Proton NMR spectra of the heteronins revealed that two olefinic bonds in the heteronin ring have the cis configurations and the nine-membered rings exist in a buckled, non-planar conformation.
