Influence of harvesting technique and maceration process on aroma and phenolic attributes of Sauvignon blanc wine.

Food Chem. 183 , 181-9, (2015)

Sauvignon blanc wines are characterised by their varietal aromas and low phenolic content. Mechanical harvesting has been shown to increase several varietal aromas. Likewise, maceration techniques hav...

Organocatalytic asymmetric direct alpha-alkynylation of cyclic beta-ketoesters.

J. Am. Chem. Soc. 129 , 441, (2007)

The first organocatalytic enantioselective direct alpha-alkynylation of beta-ketoesters and 3-acyl oxindoles is described. It is demonstrated that activated beta-halo-alkynes undergo nucleophilic acet...

Development of a gold-multifaceted catalysis approach to the synthesis of highly substituted pyrroles: mechanistic insights via Huisgen cycloaddition studies.

J. Org. Chem. 78(3) , 920-34, (2013)

A novel gold-catalyzed method for the regioselective synthesis of highly substituted pyrroles directly from oximes and alkynes was developed via independent optimization of two key steps of the proces...
