A synthesis of optically active C7- and C8 -tetrahydropyranyl subunits with suitable functionalities for futher elaboration of transfused polyether toxins was achieved from glucal acetate via the use of 2-phynylsulphonyl intermediates. The bicyclic trans,syn,trans oxane-oxepanyl substructure 26 was prepared through the application of this methodology.
通过使用2-邻苯二甲酰基磺酰基中间体,从乙酸葡糖醛中合成了具有合适官能度的光学活性C 7-和C 8-四氢吡喃基亚基,用于进一步加工输注的聚醚毒素。通过应用该方法制备了双环反式,顺式,反式,氧杂环戊烷-氧杂戊基亚结构26。
