Miguelez, Javier; Miyamura, Hiroyuki; Kobayashi, Shu published an article in 2017, the title of the article was A Polystyrene-Supported Phase-Transfer Catalyst for Asymmetric Michael Addition of Glycine-Derived Imines to α,β-Unsaturated Ketones.Related Products of 32462-30-9 And the article contains the following content:
A 2-oxopyrimidinium salt was immobilized onto a polystyrene-derived polymer to generate a heterogeneous catalyst that effectively promoted the asym. Michael addition of glycine-derived imines to α,β-unsaturated ketones. The reactions proceeded smoothly to afford the desired adducts, (S)-tert-Bu 2-[(diarylmethylidene)amino]-5-oxoalkanoates, in high yields and with high enantioselectivities (up to 92% ee). The polymer catalyst could be recovered and reused at least five times without significant loss of activity or selectivity. The experimental process involved the reaction of H-Phg(4-OH)-OH(cas: 32462-30-9).Related Products of 32462-30-9
