Ostergaard, N. published the artcileScope and limitations of chiral bis(oxazoline) ligands in the copper-catalysed asymmetric cyclopropanation of trisubstituted alkenes, Product Details of C12H14O2, the publication is Tetrahedron (2001), 57(28), 6083-6088, database is CAplus.
A series of derivatives of 3-methyl-2-buten-1-ol, Me2C:CHCH2OR (R = Ac, PhCH2, 4-O2NC6H4CO, etc.), has been used to test the scope and limitations of the copper-catalyzed asym. cyclopropanation of trisubstituted alkenes by Et diazoacetate in the presence of C2-sym. bis(oxazoline) ligands. In the best case, a trans/cis ratio of 91:9, with 92% ee for the major isomer, was obtained from the reaction of the p-methoxybenzoate derivative The highest ee was 95%, for the trans isomer of a 80:20 diastereomer mixture (acetate derivative).
