概要: The first total synthesis of bipolaramide was achieved in 47% overall yield from (2S__-)-2, 3-dihydroindole-2-carboxylic acid in three steps, utilizing thallium chemistry. Some derivatives, with dihalogeno or dialkenyl substituents at the 4 and 11 positions of (6aS__--cis)-6a, 7, 13a, 14-tetrahydropyrazino[1, 2-a : 4, 5-a']diindole-6, 13-dione have also prepared 続きを見る

概要: 金沢大学大学院自然科学研究科生理活性物質科学<br />金沢大学薬学部<br />Nucleophilic substitution reaction of 1-methoxy-6-nitroindole (1) was examined. In the reaction with sodium methoxide or sodium cyanide as a nucleophile, 2- and 3-methoxy-6-nitroindoles, and 7-cyano-6-nitroindole were obtained, respectively. A novel methylene homologation at the 3-position was found in the reaction of 1 with sodium methyl sulfide or potassium salt of diethyl malonate to give 3-methylthiomethytyl-6-nitroindole and its 2-methylthio derivative, and diethyl 2-(6-nitroindol-3-yl)methylmalonate, respectively. Possible reaction mechanism is discussed. 続きを見る
