Enantioselective alkylation of β-keto phosphonates by direct use of diaryl methanols as electrophiles

Shibata, Masashi,Ikeda, Masahiro,Motoyama, Kazuki,Miyake, Yoshihiro,Nishibayashi, Yoshiaki

supporting information, p. 9528 - 9530 (2012/10/29)

Enantioselective alkylation of β-keto phosphonates with diaryl methanols in the presence of catalytic amounts of copper(ii) trifluoromethanesulfonate and an optically active ligand gives the corresponding alkylated products in good to high yields with a high enantioselectivity.
