  Furans from Novel [3 + 2] Photocycloaddition of Alkenes to 2-(1-Alkynyl)cyclohexenones

  摘要：

  Photocycloaddition of 2-alkynyl-substituted cyclohexenones 8c-11c with isobutylene (2) and tetramethylethylene (3a) leads to tricyclic furans 15a-18a and 15b-17b; respectively, in gas chromatographic yields of similar to 90%. A suggested mechanism for this novel-process is shown in eq 2. Tetramethoxyethylene (3b) gives only oxetanes 22 and 23, and the 3-methyl-substituted ketone 12c fails to react with 2 and 3a,b. tert-Butylethylene gives [2 + 2] adduct 24 with 10c.

  Photocycloaddition of 2-(1-alkynyl)cyclohexenones 1 and 2 with alkenes 3 and 4 furnishes tetrasubstituted furans 5–8 as the only isolated products; a suggested mechanism leads from the alkyl propynyl biradical 12 to carbene 13, which then closes to the furan.

  2-（1-炔基）的光致环己烯酮1和2与烯烃3和4种配料四取代呋喃5 - 8作为唯一的分离产品; 一种建议的机理是从烷基丙炔基双自由基12到达卡宾13，然后卡宾13靠近呋喃。
