Technical Notes:
1.2nd Generation Maruoka chiral phase transfer catalyst, for enantios elective alkylation of a-amino acid derivatives, that is easily recycled by extraction with fluorous solvent.
2.Catalyst for asymmetric conjugate addition of a-substituted-a-cyanoacetates to a,ß-unsaturated acetylenic esters .
3.Phase transfer catalyzed enantioselective a-alkylation.
4.Asymmetric amination of ß-keto esters.
5.Diastereo- and enantioselective conjugate addition of a-substituted nitroacetates to maleimides .
6.Efficient asymmetric synthesis of spiro-2(3H)-furanones via phase-transfer-catalyzed alkynylation.
7.Phase-transfer catalyzed asymmetric synthesis of a,ß-unsaturated v,y-disubstituted y-lactams.
