2,8-Dithia-dibenzo[e,h]azulenes and Their 8-Oxa Analogs. Synthesis and Anti-inflammatory Activity
摘要:
Synthesis of 2,8-dithia-dibenzo[e,h]azulenes (111, X = S) and their 8-oxa analogs (111, X = 0),1 two novel classes of fused heterocyclic compounds, is described. Starting 11H-dibenzo[b,f]thiepin-10-one, 11H-dibenzo[b,f]oxepin-10-one and its 2-chloro derivative (1a-c) were oxidized to 1,2-diketones (2a-c) which subsequently reacted with 2,2'-dimethyl thiodiglycolate to form fused thiophene ring by Hinsberg cyclization reaction. Substituents at positions C(l) and C(3) were then further transformed in order to obtain aminoalkoxy derivatives 8-11. Structures of regioisomers 6c and 6d were elucidated using two-dimensional NMR techniques. All compounds with tetracyclic skeleton were tested in vitro for their anti-inflammatory activity.
