Organocatalytic Vinyl and Friedel−Crafts Alkylations with Trifluoroborate Salts [PDF]
, 2007 Herein we report the first use of vinyl and heteroaryl trifluoroborate salts as viable substrates for amine-catalyzed conjugate additions. The application of LUMO-lowering iminium catalysis has enabled the highly regio- and enantioselective 1,4-addition ...

Crystal structure of 2-(5-methoxy-1-benzofuran-3-yl)acetic acid
Acta Crystallographica Section E: Crystallographic Communications, 2015 The benzofuran residue in the title compound, C11H10O4, is essentially planar (the r.m.s. deviation for the nine non-H atoms = 0.011 Å). While the methoxy group is coplanar with the fused ring system [C—C—O—C torsion angle = 3.1 (3)°], the acetic acid ...
