  Unprecedented spirocyclization of 3-methyleneindoline-2-thiones during hydrolysis of the phytoalexin cyclobrassinin

  摘要：

  The phytoalexin cyclobrassinin is a plant defense that has additional importance since it inhibits brassinin hydrolase, a phytoalexin detoxifying enzyme produced by the plant pathogen Alternaria brassicicola. Hence, the 1,3-thiazino[6,5-b] indole scaffold of cyclobrassinin has great application as a lead structure to design potential inhibitors of brassinin detoxification. For this reason, it is necessary to determine whether A. brassicicola is able to transform cyclobrassinin. During this work new reactions of 1,3-thiazino[6,5-b] indoles and indoline-2-thiones and their unique [4+2] cycloaddition products were discovered and characterized. (C) 2012 Elsevier Ltd.

  A simple and concise approach for the synthesis of cyclobrassinin has been developed through a thiyl radical-mediated intramolecular aromatic substitution, with benzoyl peroxide as an efficient initiator and oxidant. The current method can also be utilized in the synthesis of 6 and 7-membered ring cyclobrassinin analogues in moderate to good yields. The transformation involves a formal radical 6 and
