A Decennary Review of 1,3-Dicarbonyls about Three Kinds of Mechanisms

Sulfonyl Hydrazides in Organic Synthesis: A Review of Recent Studies

“…They were three‐component reactions of ketones, amines, and sulfonyl hydrazides. Especially, 1,3‐dicarbonyls acted as important intermediates in organic synthesis. I 2 functioned as a Lewis acid for the cyclization, as well as the reaction promoter for the formation of RSI (Scheme ).…”

Recent Studies of Bifunctionalization of Simple Indoles

“…Then, carbazoles were obtained by subsequent cyclization and aromatization. 1,3‐dicarbonyls have been widely used as synthetic building blocks in organic chemistry [14d,e] . Xue and co‐worker [14c] developed the I 2 ‐promoted construction of indolo[2,3‐b]carbazoles.…”

Copper/Silver Cocatalyzed Regioselective C5–H Functionalization of 8-Aminoquinoline Amides with 1,3-Dicarbonyl Compounds

“…15,17 1,3-Dicarbonyl compounds are important and versatile synthons that are widely used in organic synthesis, and can be utilized in CDC reactions as a powerful strategy for the construction of structurally diverse molecules. 18 In such transformations, the methylenic sp 3 C-H bond in the 1,3-dicarbonyl compound is coupled with the C-H bond of another substrate in the presence of a metal catalyst. 9d,17b,19 Herein, we describe a regioselective copper/silver co-catalyzed cross-dehydrogenative coupling of the remote C5-H bond of 8-aminoquinoline amides with the methylenic sp 3 C-H bond of different 1,3-dicarbonyl compounds under an air atmosphere.…”
