diacetate (PIDA)/I2 combination towards Morin 1,4‐thiazine compounds has been developed starting from N,S‐acetals. The latter leads to “one‐step” regioselective methylene insertion without the need for traditional sulfoxide intermediates in good yields. The reaction involves easily accessible N,S‐acetals obtained from cost‐effective basic ketones and cysteamine as starting materials. This process ultimately
使用phenyliodine(III)二乙酸酯(PIDA)/ I的高效多米诺变换2组合朝向莫林1,4-噻嗪化合物已经开发选自N,S开始-缩醛。后者导致“一步式”区域选择性亚甲基插入,而无需以高收率使用传统的亚砜中间体。该反应涉及方便N,S -从成本效益的基本酮和半胱胺获得作为原料缩醛。此过程最终导致与1,4-噻嗪有关的天然产物和进一步的QSAR研究所需的熔融衍生物。
