The synthesis of the photochemical probes 6 and 7 is described. These photoprobes are analogues of dolichol and dolichol phosphate, obligatory intermediates in the N-linked glycosylation pathway in the endoplasmic reticulum. The synthesis of 6 and 7 follows a new strategy. It involves the sequential alkylation of a monoterpenoid hydroxysulfonyl dianion with allyl chlorides. The photoreactive group
描述了光化学探针 6 和 7 的合成。这些光探针是多萜醇和多萜醇磷酸盐的类似物,是内质网中 N-连接糖基化途径中的必需中间体。6 和 7 的合成遵循一个新的策略。它涉及单萜类羟基磺酰基二价阴离子与烯丙基氯的顺序烷基化。光反应性基团 3-(三氟甲基)-3-芳基二氮丙啶与完全组装的聚异戊二烯链的 β-异戊二烯基单元的羟基化甲基相连。可光活化的多萜醇类似物 6 是酵母膜多萜醇激酶的底物,酵母膜是 N-连接糖基化途径中必不可少的酶。
