  Stereoselective intramolecular cycloadditions of homochiral N-alkenoyl aryl azides

  摘要：

  Starting from the commercially available (S)-1-phenylethylamine and L-alanine benzylester, we synthesised the homochiral N-alkenoyl aryl azides 2a-2d. The intramolecular cycloaddition of unsubstituted 2a and ab gave enantiopure 3.3a-dihydro-1,2,3-triazolo[1.5-a][1.4]benzodiazepine-4(6H)-ones 3a, 3b, 4a and 4b, while phenyl-substituted 2c and 2d gave enantiopure 1.1a-dihydro-2H-azirino[2.1-c][1,4]benzodiazepine-4(6H)-ones 5c, 5d, 6c and 6d.

  Starting from the appropriate azides bearing the (S)-1-phenylethylamine and the L-alanine benzylester as chiral pendants, a facile and effective synthetic route to the title compounds in their enantiopure form was developed with excellent product yields obtained. Basic hydrolysis of the ester group of the title compounds 3a-c gave the corresponding, readily functionalisable carboxylic acids. Catalytic reduction of 2-benzyl derivatives 3c and 3f gave 4-functionalised 1,2,4,5-tetrahydro-1,4-benzodiazepin-3-ones in enantiopure forms. (C) 2007 Elsevier Ltd. All rights reserved.
