  The present invention provides innovative strategies for synthesizing pyrazole ring-functionalized benzodiazepinones. Alternative intermediates and high conversion strategies for forming alpha-aminobenzophenone intermediates involve a combination of aromatic acylation, displacement of electronegative leaving groups with amine, and then N-displacement strategies to produce the desired alpha-aminobenzophenone with primary amine functionality. Reaction strategies are then provided for converting alpha-aminobenzophenones to alpha-aminoamidobenzophenone intermediates with high yield and convenient reaction strategies. These alpha-aminoamidobenzophenone intermediates are then converted into benzodiazepinones. These benzodiazepinones are then converted to pyrazole ring functionalized benzodiazepinones through a series of innovative intermediates and/or reaction strategies.

  本发明提供了合成吡唑环功能化苯并二氮杂卓酮的创新策略。形成α-氨基二苯甲酮中间体的替代中间体和高转化策略涉及芳香酰化、用胺置换电负性离去基团以及随后采用N-置换策略以产生具有初级胺功能的所需α-氨基二苯甲酮。随后提供了将α-氨基二苯甲酮转化为高产率且反应条件便利的α-氨基酰胺二苯甲酮中间体的反应策略。这些α-氨基酰胺二苯甲酮中间体随后被转化为苯并二氮杂卓酮。这些苯并二氮杂卓酮通过一系列创新的中间体和/或反应策略转化为吡唑环功能化的苯并二氮杂卓酮。
