摘 要:Two chiral guanidines were evaluated as catalysts for the reaction of anthrone (1) with N-methylmaleimide (2). When guanidine 5 was used, the Michael adduct 4 was isolated as a major product. The best enantioselectivity (70% ee) was obtained when the reaction was carried out in THF at -20°C.Two chiral guanidines were evaluated as catalysts for the reaction of anthrone (1) with N-methylmaleimide (2).
