  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.

  3-ylideneoxindoles are synthesized from Morita-Baylis-Hillman adduct of isatin derivatives with different alcohols using FeCl3 and K-10 clay under microwave irradiation. The reaction occurs in 3 min. As this work done with the help of FeCl3, K-10 clay and microwave irradiation for short time it is an eco-friendly green synthesis. The details of the work are elaborately discussed in this letter.

  日期：——

  Five-ring-fused azepinone derivatives were synthesized serendipitously from bis-isatins via sequential 6π-electrocyclic ring closure, ring expansion, and dehydrogenation process in moderate yields (34%–47%). The reaction was carried out in diphenyl ether at 230 °C for 4–12 h under O2 balloon atmosphere.
