The synthesis of a number of new 1,4-benzodiazepin-2-ones containg the 2-thiazolyl, 5-isothiazolyl, 1-rnethyl-2-imidazolyl. 1-methyl-5-pyrazolyl, and 3,5-dimethyl-4-isoxazolyl groups in the 5-position of the benzodiazepine ring are described.

thermolysis at 200 °C gave azepino-indoles (48) and (51), the first examples of ringexpansion by an arylnitrene of benzenerings with electron-with drawing substituents. Also reported are syntheses of 3- and 4-(2-azidobenzyl)pyridines (38) and (39), and of 2-(2-azidobenzyl)thiazole (40); decomposition of these azides gave mainly polymers.

日期:1995.1
synthetic route to the phytoalexin camalexin 7 and a convergent approach to the alkaloids indolopyridocoline 8, 6,7-dihydroflavopereirine 15 and flavopereirine 9 are presented. Starting from well accessible precursors, these total syntheses highlight the preparative potential of a new method for indole synthesis based on the formation of the C2C3 bond by low-valent titanium induced reductive coupling of oxo-amides
