Michael addition of chiral β-enamino esters to MVK and acrylates promoted by Lewis acids (ZnCl2 MgBr2) or high pressure (11–14 Kbar) afforded, after hydrolytic work-up, α,α-disubstituted β-keto esters in good enantiomeric excesses.
水解处理后,路易斯酸(ZnCl 2 MgBr 2)或高压(11-14 Kbar)促进的MVK和丙烯酸酯的手性β-烯胺酯的迈克尔加成反应,得到了良好的α,α-二取代β-酮酯对映体过量。
