During the process development for multistep synthesis of Rosuvastatin calcium several impurities were obtained along with the final Rosuvastatin calcium. Out of this; synthesis of impurity A (acetone adduct) a minor impurity of Rosuvastatin calcium

Using our tridentate NHC-amidate–alkoxide Pd(II) complex, we developed a catalytic method for oxidative C–C bond cleavage of glycerol. The glycerol was degraded exclusively to formic acid and CO 2 . Two possible degradation pathways were proposed

While developing novel catalysts for carbon-carbon or carbon-heteroatom coupling (N, O, or F), we were able to introduce tridentate NHC-amidate-alkoxide palladium(II) complexes. In aqueous solution, these NHC-Pd(II) complexes showed high ability for

We report herein the development of a general and mild protocol of oxygen-promoted Pd(II) catalysis resulting in the selective cross-couplings of alkenyl- and arylboron compounds with various olefins. Unlike most cross-coupling reactions, this new me

The polysaccharide, (1»5)-α-D-ribofuranan, was synthesized by a cationic ring-opening polymerization of 1,4-anhydro-2,3-di-O-benzyl-α-D-ribopyranose with the aid of boron trifluoride etherate and subsequent debenzylation. This polysaccharide catal
