The palladium-catalyzed reaction of acetyl oximes with isocyanides was developed for the synthesis of 2H-pyrrol-2-imines. The key steps were (i) generation of an enamido-palladium(II) species, (ii) migratory double-isocyanide insertion, and (iii) cyclizat

4,5-Diphenyl-2,3-dihydro-2,3-furandione reacts with amines and hydrazines to form the amides and hydrazides of 2,3-dioxo-3,4-diphenylbutyric acid.The products exist preferentially in the form of the respective five-and six-membered ring isomers and readil

Diphenylcyclopropenone (6) reacts with 1,1,3,3-tetraalkylguanidines (7a-d) forming 2-amino-4,5-diphenyl-3H-pyrrol-3-ones 11, which are characterized as cyclomerocyanines by their spectroscopic behaviour.With guanidine (7e), 1-alkyl- and 1-phenylsubstituted guanidines (7f-h), 1,2-diphenyl, and 1,2,3-triphenylguanidine (7i,j) as well as 2-aminobenzimidazole (36) compound 6 yields exclusively 5,6-dihydro-5,6-diphenyl-4(1H)-pyrimidinones (22, 23, 28-32, 33, 34, 38), the constitution and configuration of which at C-5/C-6 is established.A mechanism for the formation of the abovementioned five- and six-membered heterocyclic systems is discussed.
