Termination of Mn(III)-based oxidative cyclizations by trapping with azide.
نویسندگان
چکیده
The radicals formed in Mn(III)-based oxidative free-radical cyclizations of beta-keto esters and malonate esters can be trapped with sodium azide and Mn(III) to give cyclic and bicyclic azides in 30-80% yield. Reduction of the azide gives bi- and tricyclic lactams. [reaction: see text]

Azide groups in high oxidation state Mn carboxylate chemistry: a new Mn(11) complex and its conversion to a Mn(25) azide complex with Me(3)SiN(3).
A new high oxidation state Mn(III/IV)(11) carboxylate complex has been prepared and then converted to a Mn(II/III)(25) azide/carboxylate cluster with Me(3)SiN(3); the Mn(25) product is the initial example of a higher oxidation state Mn azide complex not stabilized by any chelate ligands.

متن کاملTandem catalytic oxidative deacetylation of acetoacetic esters and heteroaromatic cyclizations.
One pot syntheses of furan, thiophene, and pyrrole were accomplished by oxidative deacetylation using Mn(III)/Co(II) catalysts and the Paal-Knorr reaction from 1,5-dicarbonyl compounds, which are prepared from the conjugate addition of ethyl acetoacetate to α,β-unsaturated carbonyl compounds. The oxidative deacetylation and reductive cyclization of β-ketoesters derived from ethyl acetoacetate a...

The title compound, [Mn(N(3))(2)(C(12)H(18)N(2)O)(2)]ClO(4), was synthesized from manganese(III) acetate, sodium azide and 2-[3-(dimethyl-amino)propyl-imino-meth-yl]phenol by a hydro-thermal reaction. The Mn(III) ion is hexa-coordinated by two N and two O atoms from two phenolate ligands and two N atoms from two azide ligands. The Mn(III) cation lies on an inversion centre and, as a result, the...
