The reaction of N-methyl-N'-nitroguanidine with 3-methyl-4-nitroiminotetrahydro-1,3,5-oxadiazine is a Mannich-type reaction. The reaction was catalyzed by several organic and inorganic bases at different reaction times and temperatures. Three inorganic base catalysts [potassium carbonate (K2CO3),...
Mannich-type reactioniminolactonephenolarylboronic acidMannich-type reaction of phenols with iminolactone 4, readily prepared from commercially available phenylglycine, proceeded with high stereoselectivity to give α-arylglycine derivatives. The reaction was also applicable to other electron-rich aromatic ...

An efficient and facile three-component Mannich-type reaction on purine rings was described. This reaction proceeded smoothly under the catalysis of ethylenediamine at ambient temperature in high regioselectivities with exclusive N9-alkylated products. A wide range of purine derivatives were obtained in ...
catalytic Mannich reaction can proceed with a broad variety of reactants and open clear paths for the synthesis of versatile amine synthons in the synthesis of natural product and pharmaceutical molecules. This review provides an overview of the employment of catalytic asymmetric Mannich reactions in...
