N-methylation of sulfoximines using methylboronic acid is reported. The reactions provide excellent yields in a short span of time under mild conditions. The optimized conditions were also found to be suitable for the N-alkylation of sulfoximine with different alkylboronic acids. In addition, N-methylation and cyclopropylation of the bioactive L-methionine sulfoximine derivative was demonstrated under standard
据报道,使用甲基硼酸进行了铜亚甲基亚砜亚砜的N-甲基化反应。在温和条件下,反应可在短时间内提供出色的收率。还发现优化的条件适合于用不同的烷基硼酸使亚磺酰亚胺的N-烷基化。另外,在标准反应条件下证明了生物活性的L-甲硫氨酸亚磺酰亚胺衍生物的N-甲基化和环丙基化。
