Regioselective reductive openings of mixed phenolic-benzylic acetals, using BH3·NMe3−AlCl3, was investigated, and a mechanism where the outcome is directed by the electrostatic potential of the two oxygen atoms is presented. The regioselective acetal opening was used in the synthesis of a fluorescently labeled analogue to antiproliferative xylosides. The fluorescently labeled xyloside was tested for
研究了使用BH 3 ·NMe 3 -AlCl 3的混合苯酚-苄基乙缩醛的区域选择性还原开口,并提出了由两个氧原子的静电势指示结果的机理。区域选择性缩醛开口用于合成抗增殖木糖苷的荧光标记类似物。测试了荧光标记的木糖苷在不同细胞系中的摄取,抗增殖活性和糖胺聚糖引发。木糖苷被所有细胞系吸收,但没有启动糖胺聚糖的生物合成。
