  A mild and efficient CAN mediated oxidation of Morita–Baylis–Hillman adducts of 5-methyl-N-alkylisatin to 5-formyl-N-alkylisatin

  摘要：

  A simple, mild and efficient CAN mediated oxidation of Morita-Baylis-Hillman adducts of 5-methyl-N-alkylisatins 1a-13a to 5-formyl-N-alkylisatins lb-13b under ambient reaction conditions is reported. Simple and isomerized 5-methyl-N-alkylisatin derivatives 1-4 have also been tested and failed to provide the corresponding formylated products. A plausible reaction mechanism has been proposed.

  日期：——

  Synthesis of highly functionalized allene appended oxin-dole derivatives from vinyl propargyl ether derivatives of Morita― Baylis―Hillman adducts of isatin via Claisen rearrangement has been achieved. Synthetic utility of the allene derivatives obtained has been demonstrated with the synthesis of methyl 2,5-dihydro-5-methyl-2-(1-methyl-2-oxoindolin-3-ylidene)furan-3-carboxylates in a one-pot cyclization

  已经实现了通过克莱森重排从 Morita-Baylis-Hillman 靛红加合物的乙烯基炔丙基醚衍生物合成高度官能化的丙二烯附加 oxin-dole 衍生物。所获得的丙二烯衍生物的合成效用已通过在一锅中合成 2,5-二氢-5-甲基-2-(1-甲基-2-氧代吲哚啉-3-亚基)呋喃-3-羧酸甲酯而得到证明碱性条件下的环化反应。提出了一个合理的反应机理。
