  A facile and efficient synthesis of hexahydro-1H-pyrido[2,3-b]indol-2-one scaffolds via a sequential Michael addition/amidation/reductive cyclization process

  摘要：

  A new methodology was developed for the synthesis of hexahydro-1H-pyrido[2,3-b]indol-2-one scaffolds via a sequential Michael addition/amidation/reductive cyclization process. A wide variety of products bearing a hexahydro-1H-pyrido[2,3-b]indol-2-one core with varying degrees of substitution around it, which is a key structural skeleton found in a large number of biologically active natural products and pharmaceutical compounds, were obtained smoothly with high efficiency (up to overall yield of 67%). Furthermore, their biological activities have been preliminarily demonstrated by in vitro evaluation against human prostate cancer cells PC-3, human lung cancer cells A549 and human leukemia cells k562 by the MU-based assays, using the commercially available standard drug Cisplatin as a positive control. These results suggested there is a trend that lipophilic groups improve the potency, and also suggested a carbonyl moiety located in the hexahydro-1H-pyrido[2,3-b]indol-2-one scaffolds is beneficial for the activity. The results also demonstrated that most of the compounds showed considerable cytotoxicities to these three cell lines K562, A549 and PC-3, and that hexahydro-1H-pyrido[2,3-b]indol-2-one scaffolds may be potential leads for further antitumor activity screenings.

  first phosphine‐catalyzed enantioselective γ‐addition with prochiral nucleophiles and 2,3‐butadienoates as the reaction partners has been developed. Both 3‐alkyl‐ and 3‐aryl‐substituted oxindoles could be employed in this process, which is catalyzed by a chiral phosphine that is derived from an amino acid, thus affording oxindoles that bear an all‐carbon quaternary center at the 3‐position in high yields
