dominoes: A novel, organocatalytic, Michael–Knoevenagel condensation domino reaction of ethyl 4‐diethoxyphosphoryl‐3‐oxobutanoate with various aryl‐ and aliphatic‐substituted α,β‐unsaturated aldehydes catalyzed by a chiral diarylprolinol ether has been successfully performed. The reaction proceeds in a highly enantio‐ and diastereoselective manner giving access to optically active 6‐substituted‐3‐d
通用的多米诺骨:一种成功的新型有机催化,由手性二芳基脯氨醇醚催化的4-二乙氧基磷酰基-3-氧代丁酸乙酯与各种芳基和脂肪族取代的α,β-不饱和醛的迈克尔-诺夫那格尔缩合多米诺反应。反应以高度对映体和非对映体选择性的方式进行,从而可以得到旋光的6-取代-3-二乙氧基磷酰基-2-氧代环己基3-烯基羧酸盐(请参阅方案)。
