Tr-protected amines were caught directly out of reaction mixtures by simultaneous cleavage of the protecting group. By releasing the products with ammonia the corresponding free amines were obtained in high yields and purities. The broadly applicable method of simultaneous deprotection and purification based on ionic resin capture was applied for Grignard and Mitsunobu reactions as well as amide formations
通过同时裂解保护基团,将含有 Boc-或 Tr-保护胺的产物直接从反应混合物中捕获。通过用氨释放产物,以高产率和纯度获得相应的游离胺。基于离子树脂捕获的广泛适用的同时脱保护和纯化方法被应用于格氏反应和光信反应以及酰胺形成,并显示出多平行合成的高潜力。
