The Use of Sulfur Ylides in the Synthesis of Substituted Indoles
摘要:
[GRAPHICS]This letter describes the insertion of rhodium carbenoids into thioindoles, C-10 thioindoles undergo fragmentation-coupling reactions when exposed to rhodium carbenoids. In an analogous fashion, ketoester- and malonate-substituted carbenoids have been found to insert into C-2 thioindoles, In contrast, vinylogous carbenoids were found to alkylate C-2 thioindoles at C-3.
protic solvent (methanol) these sulfides give the sulfoxides instead (except for the nitrobenzyl derivatives, where the aldehyde remains the major product). Among the α-substituted sulfides tested, the α-phenylbenzyl and the 3-cyclohexenyl sulfide give the corresponding ketone (the latter in a low yield), but the α-methylbenzyl sulfide gives the sulfoxide as the main product. The rate for singlet oxygen
