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 :Synthesis of [2.2.2]-diazabicyclic ring systems
发明人：SCHEERER JONATHAN R
权利人:COLLEGE WILLIAM & MARY
摘要:Herein we describe compositions and methods for the synthesis of [2.2.2]-diazabicyclic structures comprising a domino reaction sequence involving aldol condensation, alkene isomerization, and intramolecular hetero-Diels-Alder cycloaddition. Excellent diastereofacial control during the cycloaddition is enforced with a removable chiral phenyl aminal diketopiperazine substituent. The reaction sequence rapidly generates molecular complexity and is competent with both enolizable and non-enolizable aldehyde substrates. This method provides an efficient route to [2.2.2]-diazabicyclic structures, common to bioactive prenylated indole alkaloids such as the brevianamides and stephacidins.
