convergent synthesis of a regioselectively 6(V)-sulfated mannopentasaccharide derivative 1c, octyl 6-O-sulfo-alpha-D-mannopyranosyl-(1-->3)-alpha-D-mannopyranosyl-(1-->3)-alpha-d-m annopyranosyl-(1-->3)-alpha-D-mannopyranosyl-(1-->2)-alpha-D-mannopyranoside, was achieved by a '3 + 2' strategy. The target was designed to mimic the promising anticancer agent PI-88 and was obtained from the building blocks
一种高效且收敛的区域选择性合成6(V)-硫酸化的甘露糖衍生物1c,辛基6-O-磺基-α-D-甘露吡喃糖基-(1-> 3)-α-D-甘露吡喃糖基-(1-> 3)-α-dm氨基吡喃糖基-(1→3)-α-D-甘露吡喃糖基-(1→2)-α-D-甘露吡喃糖苷是通过'3 + 2'策略获得的。该靶标旨在模仿有希望的抗癌药PI-88,并从3,4,6-三-O-苯甲酰基-α-D-甘露吡喃糖辛基,2,4,6-三烯丙基烯丙基中获得。在TMSOTf下-苯甲酰基-3-O-(4-甲氧基苄基)-α-D-甘露吡喃糖苷和6-O-乙酰基-2,3,4-三-O-苯甲酰基-α-D-甘露吡喃糖基三氯乙酰亚胺酸酯(11) -催化的糖基化条件。根据绒毛膜尿囊膜(CAM)模型研究,化合物1c显示出适度的抗血管生成活性。
