Substituted 5,6-dihydro-4H-1,3-oxazines are prepared by the acid-catalyzed amidoalkylation of the terminal olefins. 5,6-Dihydro-4H-oxazines undergo further transformations involving the hetero-ring and/or the substituent leading to alkyl amino-substituted 5,6-dihydro-4H-1,3-dihydrooxazines and/or to ring-opened products, 3-hydroxypropylamides.
取代的5,6-二氢-4H-1,3-恶嗪是通过末端烯烃的酸催化的酰胺基烷基化反应制备的。5,6-二氢-4H-恶嗪经历进一步的转化,涉及杂环和/或取代基,导致烷基氨基取代的5,6-二氢-4H-1,3-二氢恶嗪和/或产生开环产物, 3-羟丙基酰胺。
