2007 Polyphenylalkane derivatives Q 0720 Diarylmethanols by Catalyzed Asymmetric Aryl Transfer Reactions onto Alde- hydes Using Boronic Acids as Aryl Source. — The catalytic synthesis of 1,1'-disub- stituted diarylmethanols in the presence of a planar-chiral ferrocene catalyst is reported. Generally, high enantioselectivities and good yields are achieved. Heteroaromatic al- dehydes and heteroaromatic boronic acids also react well. By appropriate combination of aldehyde (II) and boronic acid (I), both enantiomers of the desired products are ac- cessible using the same catalyst. — (SCHMIDT, F.; RUDOLPH, J.; BOLM*, C.; Adv.
