4-羟基-2,2-二甲基环己酮 | (+/-)-4-Hydroxy-2,2-dimethyl-1-cyclohexanone | 123214-39-1 | C8H14O2 | 142.198 |
The exploration of catalytic potential of natural amino acid salt in activation of 1,3-dicarbonyls was carried out, in which maleimides and 2-(2-oxoindolin-3-ylidene)malononitriles were found to be good electrophiles and afforded the desired products with excellent yield and moderate optical purity. Control experiments showed that the secondary amino group of barium (S)-prolinate is critical to the catalytic activity as well as enantiocontrol, thus revealed an enamine activation mechanism is possible in the present methodology.
