Palladium(II)-catalyzed dicarboxymethylation of chiral allylic alcohols:
Published at:Tetrahedron Letters 51 (2010) 3514–3517
This manuscript describes the extension of Stille’s palladium-catalyzed olefin dicarbonylation reaction to chiral allylic alcohols with chirality transfer to afford the corresponding chiral alcohol functionalized with bis-carbomethoxy esters, containing three contiguous chiral centers, in good to excellent diastereoselectivities
(78–98%).

Liquid distribution mat made of enhanced cellulosic fibers
Published at:United States Patent 7686921
A liquid distribution mat that is a wet-laid mat of enhanced cellulosic fibers that are cellulosic fibers cross-linked in sheet form, as well as methods of making the liquid distribution mat. The liquid distribution mat has high vertical wicking properties and excellent structural integrity in both wet and dry states. The liquid distribution mat is suitable for use in an absorbent article. When used in an absorbent article such as a baby diaper, the liquid distribution mat rapidly acquires and transports bodily discharges from the point of insult to other regions of the absorbent article, thereby maximizing the utilization of the absorbent article
