[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...

To maximize therapeutic effects, targeted delivery of nucleic acids (e.g., DNA and RNA) in their appropriate intracellular targets is highly desirable. In this study, primary amines of a model polymeric nonviral carrier, polyethylenimine (PEI), at two molecular weights (0.8 and...

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...
