We developed a new protecting group, i.e., cis-[4-[[(4-methoxytrityl)sulfenyl]oxy]tetrahydrofuran-3-yl]oxycarbonyl (MTFOC), which could be removed under neutral conditions involving the oxidative removal of the MMTrS group followed by the self-cyclization of the resulting intermediate. The introduction of the protecting group into the 5′-hydroxyl group of a thymidine derivative and its deprotection
我们开发了一种新的保护基团,即顺式-[4-[[(4-甲氧基三苯甲基)硫基]氧基]四氢呋喃-3-基]氧羰基 (MTFOC),它可以在中性条件下被去除,包括 MMTrS 的氧化去除基团,然后是所得中间体的自环化。研究了在胸苷衍生物的5'-羟基上引入保护基及其脱保护。
