摘要:An object of the present invention is to provide a method for synthesis of keto acids by hydration of an acetylene compound (acetylene-carboxylic acids) under mild conditions free from harmful mercury catalysts and a method for synthesis of amino acids from acetylene-carboxylic acids in a single container (one-pot or tandem synthesis). In one embodiment of the method according to the present invention for synthesis of keto acids, acetylene-carboxylic acids is hydrated in the presence of a metal salt represented by General Formula (1), n nwhere M 1 represents an element in Group VIII, IX, or X of the periodic table, and X 1 , X 2 , or X 3 ligand represents halogen, H 2 O, or a solvent molecule, and k represents a valence of a cation species, and Y represents an anion species, and L represents a valence of the anion species, and each of K and L independently represents 1 or 2, and k×m=L×n.

标题 :Process for the synthesis of heterocycles from palladocyclic complexes
摘要:Heterocylic rings are synthesised from palladocyclic complexes by reaction with alkynes, characterised in that the palladocyclic complexes are employed in the form of iodo or cationic complexes. The process applies in particular to the synthesis of nitrogenous heterocyclic rings.
