- Copper(I)-catalyzed asymmetric desymmetrization: Synthesis of five-membered-ring compounds containing all-carbon quaternary stereocenters
-
A highly stereoselective catalytic alkylation sequence for the synthesis of highly functionalized and versatile five-membered-ring compounds bearing all-carbon quaternary stereocenters was developed. Enantioselective desymmetrization of achiral cyclopentene-1,3-diones was thus executed by chiral Cu-phosphoramidite catalysts. A variety of complicated cyclopentane derivatives can be synthesized with excellent stereoselectivities using a low catalyst loading in a one-pot operation.

- SILINANE COMPOUNDS AS CYSTEINE PROTEASE INHIBITORS
-
The present invention is directed to compounds that are inhibitors of cysteine proteases, in particular, cathepsins B, K, L, F, and S and are therefore useful in treating diseases mediated by these proteases. The present invention is also directed to pharmaceutical compositions comprising these compounds and processes for preparing them. The present invention is also directed to the use of these inhibitors in combination with a therapy that causes a deleterious immune response in patients receiving the therapy.

- Synthesis of the marine compound (2R,5Z,9Z)-2-methoxyhexacosa-5,9-dienoic acid via a lipase-catalyzed resolution and a novel O-alkylation protocol
-
The title compound has been synthesized by a facile route starting from 4-pentyn-1-ol. The enantioselectivity was attained by a strategy involving a lipase-catalyzed acetylation of a solid-phase immobilized long chain α-hydroxy acid. Another important feature of the synthesis was the formulation of an efficient HgO-catalyzed O-methylation of the α-hydroxy acids which proceeded without any racemization. The alkylation protocol was also highly efficient for selective mono-methylation/benzylation of symmetrical diols.

- Process for preparing α-aminoalcohols
-
Process for preparing an α-aminoalcohol of formula EQU1 wherein R represents hydrogen or alkyl of from 1 to 5 carbon atoms, which comprises contacting a compound of formula EQU2 wherein R has the same meaning as above, with an alcohol of formula R'-OH wherein R' represents benzyl or the group EQU3 in which R" and R"' are independently selected from hydrogen and alkyl of from 1 to 4 carbon atoms in an organic solvent, in the presence of a basic catalyst, at from about 140° to about 170°C., treating the obtained product of formula EQU4 wherein R and R' have the above meanings, with at least an equimolecular amount of a p-toluene-sulfonyl halide, at from about -5° to about 20°C. in the presence of a tertiary organic nitrogen-containing base and reacting in a closed system the resulting compound of formula EQU5 wherein R and R' are as above defined, with an excess of gaseous ammonia, in the presence of an inert organic solvent, at from about 95° to about 120°C. and recovering the resulting product as its acid addition salt.
