Spiro[4.4]non- and spiro[4.5]dec-2-ene-1,6-diones [2; n = 0 and 1] were prepared in moderate to high enantiomeric purities via asymmetric allylation of enamines 6 and ketal derivatives 7 and 8 formed from keto-esters 5, followed by a carbanionic cyclization process.
螺[4.4]非螺和螺[4.5]癸-2-烯-1,6-二酮[ 2 ; n = 0和1]通过烯胺6和由酮酸酯5形成的缩酮衍生物7和8的不对称烯丙基化,以中等至高对映体纯度进行制备,然后进行碳负离子环化过程。

日期:1991.1
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.
Asymmetric nucleophilic addition of chiral β - enamino esters to acrylonitrile

DOI:10.1016/s0957-4166(00)86008-5
日期:1993.1
β - enamino esters derived from β - keto esters and (S)-1- phenylethytamine, react with acrylonitrile in the presence of a Lewis acid or under high pressure activation to give, after hydrolytic work up, α,α- disubstituted β - keto esters 4 (EWG=CN) in enantiomeric excesses close lo 90%.
