alkylene malonates [19]. More recently, the complex from 2,2′,6,6′-tetrakis[(4S)-phenyloxazolin-2-yl]-biphenyl and Pd(II) was reported to show excellent catalytic activities and enantioselectivities in the Wacker-type cyclization of allylphenols with up to 99% ee [20]. Despite their great application
