Ochiai, Shiho published the artcileSynthesis of Benzylidenesuccinates through Rhodium(III)-Catalyzed C-H Alkenylation with Itaconate, Quality Control of 617-52-7, the publication is Asian Journal of Organic Chemistry (2022), 11(2), e202100774, database is CAplus.
The dehydrogenative coupling of aromatic amides, e.g., (1-methyl-1H-indol-2-yl)-1-pyrrolidinylmethanone with di-Me itaconate proceeds smoothly under rhodium catalysis through ortho C-H bond cleavage directed by their amide group to produce benzylidenesuccinates, e.g., I. Aromatic carboxylic acids, e.g., 2-thiophenecarboxylic acid including benzoic and phthalic acids also couple with the itaconate to give 1 : 2 coupling products, e.g., II predominantly. Benzylidenesuccinic acid derivatives have been known to show various biol. activities. These reactions provide easy access to the important structures.
