[Structure: see text] A powerful Ti-crossed Claisen condensation between ketene silyl acetals (KSAs) and acid chlorides was successfully performed to give alpha-monoalkylated esters and thermodynamically unfavorable (less accessible) alpha,alpha-dialkylated beta-keto esters in good yield (46 examples; 41-98% yield). A closely

A generic LC-MS/MS method was developed for the analysis of potentially genotoxic alkyl halides. A broad selection of alkyl halides were derivatized using 4-dimethylaminopyridine in acetonitrile. The reaction conditions for derivatization, i.e., solvent, reaction time, temperature and concentration of alkyl

An effective method for grafting L-lactide (LA) from unmodified cellulose by ring-opening polymerization (ROP) in homogeneous mild conditions is presented. By using 4-dimethylaminopyridine (DMAP) as an organic catalyst, cellulose-graft-poly(L-lactide) (cellulose-g-PLLA) copolymers with a molar substitution (MS(PLLA)) of PLLA in a

Catalysts hold promise as tools for chemical protein modification. However, the application of catalysts or catalyst-mediated reactions to proteins has only recently begun to be addressed, mainly in in vitro systems. By radically improving the affinity-guided DMAP (4-dimethylaminopyridine) (AGD) catalysts
