Gold-catalyzed hydroarylation of alkynes
Reetz, Manfred T.,Sommer, Knut
, p. 3485 - 3496 (2003)
The hydroarylation of aryl-substituted alkynes by substituted electron-rich arenes is catalyzed by AuCl3 activated by such silver salts as AgSbF6. In the case of terminal alkynes, complete regioselectivity in favor of the 1,1-disubstituted olefin is observed. In the case of electron-poor alkynes such as acetylenecarboxylic acid ester, gold(I) complexes such as [Ph3PAuCl] activated by Ag salts or BF 3·OEt2 are the best catalysts, resulting in opposite regioselectivity and high degrees of (Z)-selectivity.

Kinetic resolution of (E)-4-(2′,5′-dimethylphenyl)-but-3-en-2-ol and (E)-4-(benzo[d][1′,3′]dioxol-5′-yl)-but-3-en-2-ol through lipase-catalyzed transesterification

Abstract A short and efficient chemoenzymatic pathway was developed to produce both enantiomeric forms of allyl alcohols possessing a bulky aromatic substituent at the stereogenic center, namely (E)-4-(2′,5′-dimethylphenyl)-but-3-en-2-ol and (E)-4-(benzo[
