We describe an efficient multicomponent reaction for the preparation of β-unsaturated α-amino esters by ytterbium triflate catalyzed reaction of potassium organotrifluoroborate salts, aniline and ethyl glyoxalate. The synthetic viability of this protocol was demonstrated by moderate to high yields, short reaction time ranging from 0.5 to 12 h, and efficiency with respect to substrate scope.
我们描述了通过三氟甲磺酸late催化的有机三氟硼酸钾盐,苯胺和乙二醛酸乙酯的反应来制备β-不饱和α-氨基酯的有效多组分反应。该方案的合成可行性通过中等至高收率,0.5至12小时的短反应时间以及相对于底物范围的效率证明。
