Synthesis of imidazolidin-2-ones employing dialkyl carbonates as an ecofriendly carbonylation source

A new approach to the synthesis of imidazolidin-2-ones by carbonylation of vicinal diamines with dialkyl carbonates using Pb(NO3)2 and Cu(ii) salts as catalysts has been described in the present protocol. A comparative study using Cu(ii) salts and Pb(NO3)2 as catalysts has suggested Cu(NO3)2 and CuCl 2·2H2O salts to be as promising as Pb(NO 3)2 and can replace the latter in the carbonylation reactions employing dialkyl carbonates. the Partner Organisations 2014.

Syntheses with α-Metalated Isocyanides, XLV. - Reactions of α-Metalated Isocyanides with Some 1,3-Dipoles

Reaction of α-metalated isocyanides 1a-c, f with alkylideneamine oxides (nitrones) 4 affords the 2-imidazolidinones 8.The 6-metalated 2,3-dihydro-4H-1,2,5-oxadiazine of type 5 is postulated as decisive intermediate. - Benzonitrile oxide (17) reacts analogously with 1a and 1b to give 4-imidazolin-2-ones 18 and with 1e to give the 3-imidazolin-2-one 19. - Phenyl azide (20) reacts with two moles of 1b to give 5-(benzylidenamino)-4H,5H-1,2,3-triazoline 24.The reaction course is discussed.
