Azoniaazulenes. Part 7. Functionalisation of 10H-azepino[1,2-a]indoles
摘要:
Direct functionalisation of azepinoindole 7 is described. Electrophilic attack by bromine, and by the Vilsmeier, Mannich, and Friedel-Crafts reagents gives 11 substituted azepinoindoles 8 and 11-14. From the bromo compound 8 an 11-lithioazepinoindole was obtained. With tert-butyllithium the azepinoindole 7 gave an allylic anion 36, which with trimethylsilyl (TMS) chloride gave the 8H-8-TMS derivative 16 and the 10H-8,10-bis-TMS derivative 17, for which an X-ray structure is provided. Alkylation of anion 36 gave mixtures of 8H-8-alkyl- and 10H-10-alkyl derivatives 18-25, while further lithiation of compound 16 and alkylation gave-mixtures of 8,8- and 8,10-disubstituted compounds 26-33. Decomposition of azide 43 gave eight identified products 44, 45, 47-51 and 54.

Photochemical reaction of methanol with 1OH-azepino[1,2-a]indoles gives three types of product derived from addition of methanol to the diene system; one of the products has undergone a skeletal rearrangement.
