These dienes reacted with the enamine derived from cyclopentanone and pyrrolidine to afford the corresponding cyclopenteno-fused 6H-dibenzo[b,d]pyran-6-ones, most likely via a domino inverseelectrondemandDiels–Alder (IEDDA)/elimination/transfer hydrogenation sequence. The parent diene (EWG = CO2Me, no substituents) was reacted with a range of electron-rich dienophiles (mostly enamines) to afford
合成了一组香豆素稠合的缺电子的1,3-二烯,它们在二烯单元末端的吸电子基团(EWG)的性质不同(当EWG = CO 2 Me时),其性质和取代基的位置。这些二烯与衍生自环戊酮和吡咯烷的烯胺反应,生成相应的环戊烯稠合的6 H-二苯并[ b,d ]吡喃-6-酮,很可能是通过多米诺逆电子需求Diels-Alder(IEDDA)/消除/转移加氢顺序。使母体二烯(EWG = CO 2 Me,无取代基)与一系列富电子的亲二烯体(主要是烯胺)反应,得到相应的6 H-二苯并[ b],d ] pyran-6-ones或它们的未脱氢前体,用合适的氧化剂处理后会被芳香化。烯胺可以在反应之前合成或就地产生。报道了30种二苯并吡喃酮的合成。
Electroreductive hydrocoupling of activated olefins with ketones or aldehydes in the presence of trimethylchlorosilane
Electroreductive crossed hydrocoupling of α,β-unsaturated esters with aldehydes or ketones in the presence of trimethylchlorosilane afforded γ-lactones in good yields. Similarly, α,β-unsaturated nitriles gave γ-hydroxynitriles in high yields.
