(Chemical Equation Presented) Without mercury or thallium: A new umpoled nucleophilic acylation reagent is formed in the direct deprotonation of 1,3,5-trimethyl-1,3,5-triazacyclohexane with butyllithium. The carbanionic center is flanked by two amino grou

The formose reaction, one of the oldest name reactions in organic chemistry, uses formaldehyde as a C1 unit resulting in different monosaccharides and sugar-like compounds. Nucleophilic formyl elongation is an attractive option to obtain 1,2-fu

A new primary amine catalyst for the asymmetric α-hydroxylation and α-fluorination of α-branched aldehydes is described. The products of the title transformations are generated in excellent yields with high enantioselectivities. Both processes can be performed within short reaction times and on gram scale. The similarity in results obtained in both reactions, combined with computational evidence, implies a common basis for stereoinduction and the possibility of a general catalytic mechanism for α-functionalizations. Promising initial results in α-amination and α-chlorination reactions support this hypothesis.
