derivatives bearing a photoreactive group at D-ring were regioselectively synthesized by applying our original synthetic reactions such as acid-catalyzed rearrangement of 2-tosyl group of 3,4-disubstituted 2-tosylpyrroles to 5-position, regioselective preparation of 3,4-disubstituted 5-tosylpyrrolinones, and their Wittig-type new coupling reaction with 2-formyl pyrrole.
通过应用我们原始的合成反应,如酸催化 3,4-二取代 2-甲苯磺酰基吡咯的 2-甲苯磺酰基重排到 5-位,在 D-环上带有光反应基团的藻胆素衍生物的 C/D-环组分是区域选择性合成的。 ,区域选择性制备 3,4-二取代 5-甲苯磺酰基吡咯啉酮,以及它们与 2-甲酰基吡咯的 Wittig 型新偶联反应。
