摘要
Ba'zinc'ga! A zinc-catalyzed sequence involving a cyclization with a subsequent C-O, C-N, or C-C bond formation enables the preparation of a variety of valuable furfuryl ethers (with alcohols) and unsymmetrically substituted triarylmethane derivatives (with azoles or arenes). ZnCl2 serves as the catalyst. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
