The amidation reaction of carboxylicacid derivatives was developed using sulfur trioxide pyridinecomplex (SO3·py) as a commercially available and easily handled oxidant. This method could be applied to the reaction of various aromatic and aliphatic carboxylicacids, including optically active ones, with formamide derivatives to afford the corresponding amides in good to high yields.

Treatment of allylic and benzylichalides with N,N-dimethylcarbamoyl(trimethyl)silane in the presence of tetrakis(triphenylphosphine)palladium(0) affords tertiary amides, which arise from the replacement of the halogen by the N,N-dimethylcarbamoyl group.

Of experiments on the CLAISEN rearrangement of allylic- and benzylic-alcohols with 1-dimethylamino-1-methoxy-ethylene, communicated earlier in preliminary form, we still owe the description of the experimental details. Here they are.
The first highly enantioselective α‐fluorination of 2‐acylimidazoles utilizing iridium catalysis has been accomplished. This transformation features mild conditions and a remarkably broad substrate scope, providing an efficient and highly enantioselective approach to obtain a wide range of fluorine‐containing 2‐acylimidazoles which are found in a variety of bioactive compounds and prodrugs.
