Treatment of N-(2-hydroxy-3,5-dimethylbenzyl)-β-aminopropanoic acid with dehydrating agents gives 3,4-dihydro-3-(2-hydroxy-3,6-dimethylbenzyl)-6,8-dimethyl-2H-1,3 benzoxazine; a reaction pathway is proposed, involving loss of keten.
用脱水剂处理N-(2-羟基-3,5-二甲基苄基)-β-氨基丙酸得到3,4-二氢-3-(2-羟基-3,6-二甲基苄基)-6,8-二甲基- 2 H -1,3苯并恶嗪; 提出了一种反应途径,涉及酮的损失。
