system that combines metal catalysis (AgOTf) and the employment of catalytic amount of organocatalyst (PPh3) has been successfully employed in the three-component reaction of 2-alkynylbenzaldehyde, amine, and α,β-unsaturated ketone. This reaction proceeds smoothly in THF under mild conditions leading to the functionalized 1,2-dihydroisoquinolines in moderate to good yields.
结合了金属催化(AgOTf)和催化量的有机催化剂(PPh 3)的两组分活化系统已成功用于2-炔基苯甲醛,胺和α,β-不饱和酮的三组分反应。该反应在温和的条件下在THF中顺利进行,从而以中等至良好的收率得到官能化的1,2-二氢异喹啉。
