中文摘要 | the asymmetric michael addition of aldehydes to nitroolefins was investigated using l-prolinamide derivatives of 2-(2'-piperidinyl)pyridine as catalyst and a variety of phenols as co-catalyst. extensive screening toward the effect of prolinamides, phenols, and solvents on this transformation revealed that a combination of (s)-2-(2'-piperidinyl)pyridine-derived trans-4-hydroxy-l-prolinamide 2c, (s)-1,1'-bi-2-naphthol, and dichloromethane was a promising system. this system was shown to be amenable to a rich variety of aldehydes and nitroolefins and afforded the nitroaldehyde products with excellent yield, enantiomeric excess (up to 99%) and diastereoselectivity ratio (up to 99/1), even in the case of 1 mol % catalyst loading and 1.5 equiv of aldehydes. |
