Palladium-catalyzed aminocarbonylations of alkenyl chlorides, bromides, and triflates were investigated using Mo(CO)6 as a solid carbon monoxide source. The reactions afforded moderate to good yields producing a wide variety of acrylamides afte

Previously obtained picolinic acid benzylamide is a potent anticonvulsant with low neurotoxicity. In search for new effective anticonvulsants twelve new benzylamides (1-12) were synthesized and preliminary evaluated in the Anticonvulsant Screening Program (ASP) of Antiepileptic Drug Development Program (ADDP) of NIH. Two of them appeared the most promising: 1- cyclopentenecarboxylic acid benzylamide (1- Cpc-BZA) (9) showed MES ED 50 = 85,36 mg/kg (PI = 2,49), scPTZ ED50 = 1,37 mg/kg (PI = 1,37), 6Hz-EST ED50 = 50,29 mg/kg and cyclopentanecarboxylic acid benzylamide (Cpc-BZA) (11) showed pilocarpine ED50 = 154.75 mg/kg and pilocarpine ED97 = 270.95 mg/kg.

A method for synthesizing carboxylic acids and their derivatives from aldehydes and ketones via α-chloro-α-sulfonyl ketones is described.Acyclic α-chloro-α-sulfonyl ketones were synthesized from aldehydes and 1-chloroalkyl p-tolyl sulfoxides with carbon-carbon coupling in good overall yields.Cyclic α-chloro-α-sulfonyl ketones were synthesized from cyclic ketones in three steps in high overall yields.The Favorskii rearrangement of both acyclic and cyclic α-chloro-α-sulfonyl ketones with sodium hydride in the presence of amine gave β-sulfonyl amides with skeletal rearrangement in good to excellent yield.Amides and α,β-unsaturated amides were synthesized from the β-sulfonyl amides.Treatment of the cyclic α-chloro-α-sulfonyl ketones with alkoxides and hydroxide gave carboxylic esters and acids with cleavage of the ring in good to excellent yields.
