herein the use of glycerol as an efficient, safe and recyclable solvent in the one-pot hetero-Diels–Alder (HDA) reaction of (R)-citronellal with substituted arylamines. The catalyst-free reactions proceed easily using glycerol at 90 °C and the corresponding octahydroacridines (OHAs) were obtained in good to excellent yields by simply decantation of products. After removing the products, glycerol was directly
我们在本文中描述了在(R)香茅醛与取代的芳基胺的一锅杂Diels-Alder(HDA)反应中,甘油作为一种有效,安全和可循环使用的溶剂的用途。使用甘油在90°C下轻松进行无催化剂反应,并通过简单地倾析产物,以良好或优异的收率获得相应的八氢ac啶(OHA)。除去产物后,将甘油直接重复用于进一步的HDA反应,而不会失去活性。
