from Arundo donax were synthesized using the first ynindole Diels–Alder reaction. The alkaloids are chiral, having stable enantiomeric conformations with half‐lives of racemization of t1/2=4150–25100 seconds at room temperature. Their absolute stereochemistry was determined using the exciton chirality method.
使用第一个炔吲哚Diels-Alder反应合成了来自Arundo donax的双(吲哚)生物碱。生物碱是手性的,在室温下具有稳定的对映异构构象,消旋半衰期为t 1/2 = 4150–25100秒。使用激子手性法确定它们的绝对立体化学。
