A new method converting thioamides to the synthetically useful precursor, 2-substituted dihydro-1,3-oxazine, is described, in which the corresponding S-methyl thiouronium salts are refluxed with 4-amino-4-methyl-2-pentanol in tBuOH or CH2Cl2 to give the products in high yields.
描述了一种将硫代酰胺转化为合成有用的前体 2-取代二氢-1,3-恶嗪的新方法,其中相应的 S-甲基硫脲盐与 4-氨基-4-甲基-2-戊醇在 tBuOH 中回流或 CH2Cl2 以高产率得到产物。
