An alkoxyamine linker was applied for the solid-phase synthesis of benzothiazoles. The substrate was anchored by aldoxime linkage and products were cleaved from the solid-support by aldoxime–imine exchange coupled with air-oxidation under the weakly acidic conditions. The tether is highly robust under Mitsunobu reaction, nucleophilic substitution reaction, and Pd-catalyzed reaction conditions.
将烷氧基胺接头用于苯并噻唑的固相合成。底物通过醛肟键固定,在弱酸性条件下,通过醛肟-亚胺交换结合空气氧化作用,将产物从固相支持物上裂解下来。该系链在Mitsunobu反应,亲核取代反应和Pd催化的反应条件下具有很高的鲁棒性。
