  New Efficient Synthesis of 1,4-Benzodiazepin-5-ones by Catalytic Aza-Wittig Reaction

  摘要：

  1,4-Benzodiazepin-5-ones were synthesized in 71-89% yields from 2-isocyanato-N-(2-oxoalkyl)benzamides via a new catalytic intramolecular aza-Wittig reaction. Starting from easily accessible phthalic anhydride and alpha-arylamino ketones, the corresponding 2-{[(2-oxoalkyl) amino] carbonyl} benzoic acids underwent sequential formation of the acid azide and Curtis rearrangement to give 2-isocyanato-N-(2-oxoalkyl) benzamides that were reacted directly to give the final 2,4-diaryl-3,4-dihydro-5H-1,4-benzodiazepin-5-ones and 4-aryl-2-tert-butyl- 3,4-dihydro-5H-1,4-benzodiazepin-5-ones.

  A number of optically active amino alcohols were synthesized by direct asymmetric transfer hydrogenation of the corresponding amino ketones with good-to-high enantiomeric excesses (up to 95%) and excellent yields (up to 93% ). When the range of substrates was broadened to include α-sulfonamido ketones or α-keto sulfones, the corresponding products were obtained with 100% enantiomeric excesses. The
