The borohydride catalyzed boranereduction of 3-nitrochromenes provided a facile route to a variety of 3-hydroxylamino- 5 and 3-amino-2H-1-benzopyranes 6. Reduction with methoxyborohydride species, on the other hand, provided 3-nitrochromans 2,4.
硼氢化物催化的3-硝基苯并二氢硼烷还原为各种3-羟基羟氨基5和3-氨基-2 H -1-苯并吡喃提供了简便的途径。另一方面,用甲氧基硼氢化物还原可提供3-硝基苯并二氢吡喃2 ,4。
