moieties are frequently used in medicinal chemistry. The synthesis of derivatives bearing a free NH often requires the use of a protection method. A literature search reveals very few protection/deprotection methods for cyclic carbamates. In this paper, we described different methods applicable to 2(3H)-benzoxazolone and 2(3H)-benzothiazolone.
侧接有杂环或脂族部分的环状氨基甲酸酯通常用于药物化学中。带有游离NH的衍生物的合成通常需要使用保护方法。文献检索显示,很少有针对环状氨基甲酸酯的保护/脱保护方法。在本文中,我们描述了适用于2(3H)-苯并恶唑酮和2(3H)-苯并噻唑酮的不同方法。
