The octahydropyrano[3,2-b]pyrrole derivatives are synthesized by a double reductive amination from pyranose derivatives of nono-2,5-diuloses and octos-4-uloses and various amines. The cyclization proceeded smoothly in the presence of sodium triacetoxyborohydride to produce a series of novel fused N-heterobicyclic compounds with high stereoselectivity.
八氢吡咯并[3,2-b]吡咯衍生物是通过来自壬糖衍生物的非 2,5-二醛和辛糖-4-醛以及各种胺的双重还原胺化反应合成的。在三乙酰氧基硼氢化钠的存在下，环化反应顺利进行，生成了一系列具有高立体选择性的新型稠合 N-杂双环化合物。
