Selective synthesis of pyrimidines from cinnamyl alcohols and amidines using the heterogeneous OMS-2 catalyst

Herein, an efficient aerobic oxidative synthesis of pyrimidines was carried out using cinnamyl alcohols and amidines catalyzed by manganese oxide octahedral molecular sieve (OMS-2). The heterogeneous catalytic method features base-/additive-free conditions, wide substrate scope, use of O2 as a green oxidant, and simple operation. Moreover, the OMS-2 catalyst prepared by the conventional reflux method demonstrates catalytic selectivity, activity, and excellent recyclability.

Manganese-Catalyzed Multicomponent Synthesis of Pyrimidines from Alcohols and Amidines

The development of catalytic reactions for synthesizing different compounds from alcohols to save fossil carbon feedstock and reduce CO2emissions is of high importance. Replacing rare noble metals with abundantly available 3d metals is equally important. We report a manganese-complex-catalyzed multicomponent synthesis of pyrimidines from amidines and up to three alcohols. Our reaction proceeds through condensation and dehydrogenation steps, permitting selective C?C and C?N bond formations. β-Alkylation reactions are used to multiply alkylate secondary alcohols with two different primary alcohols to synthesize fully substituted pyrimidines in a one-pot process. Our PN5P-Mn-pincer complexes efficiently catalyze this multicomponent process. A comparison of our manganese catalysts with related cobalt catalysts indicates that manganese shows a reactivity similar to that of iridium but not cobalt. This analogy could be used to develop further (de)hydrogenation reactions with manganese complexes.
