The synthesis of glucuronides derived from mianserin and its 6-aza analogue (Org 3770) is described. Several methods were investigated. The most successful approach was the coupling of 1,2,3,4,10,14b-hexahydro-8-hydroxy-2-(trifluoroacetyl)dibenzo[c,f]pyrazino[1,2-a]azepine or its 6-aza analogue with methyl [trichloroethanimidoyl 2,3,4-tris-O-(phenylmethyl)-α-D-glucopyranosid]uronate catalyzed by BF3
描述了衍生自mianserin及其6-氮杂类似物(Org 3770)的葡糖醛酸苷的合成。研究了几种方法。最成功的方法是将1,2,3,4,10,14b-六氢-8-羟基-2-(三氟乙酰基)二苯并[ c,f ]吡嗪并[1,2- a ]氮杂或其6- BF 3催化的[三氯乙亚氨基甲基2,3,4-三-O-(苯甲基)-α-D-吡喃葡萄糖苷]尿酸酯的氮杂类似物。获得了完全保护的糖苷,为非对映异构体β/α混合物。脱保护后,合成了2-脱甲基米色林和2-脱甲基-Org 3770的葡糖醛酸苷。对应的N(2)-甲基类似物通过还原甲基化获得。合成的β-葡萄糖醛酸苷与棉仁素和Org 3770的分离代谢产物相同。
