Pd(OAc)2 combined with nitrogen-containing ligands catalyzed the cyclization of (Z)-N-allylic 2-alkynamides in acetic acid to afford the α-(Z)-acetoxyalkylidene-γ-butyrolactams in high yield and high stereoselectivity. When chiral nitrogen-cont

Eight imidazole alcaloids were isolated from Cynometra lujae: anantine, noranantine, cynometrine, isoanantine, isocynometrine, isocynodine, hydroxyanantine and cynolujine.The syntheses of isoanantine and isocynometrine were achieved starting from 1-methyl-5-methoxycarbonyl imidazole and those of anantine and cynometrine starting from 1-methyl-4-methoxycarbonyl imidazole.
