An Efficient Indium-Mediated Synthesis of α-Cyano-β-Ethylenic Secondary Alcohols in Water

Publikováno v: Synthetic Communications. 26:3179-3191

Coupling of aldehydes with 3-bromo-1-cyano-1-propene, using indium in water, is a very convenient method to prepare α-cyano-β-ethylenic secondary alcohols.

Stereoselective Cycloaddition on Carbohydrates for the Synthesis of New Bicyclic Oxazolidines Bearing a Quaternary Bridgehead

Autor: Celine Cano, George Bashiardes, Bernard Mauze

Publikováno v: ChemInform. 36

A new carbohydrate nitrone intramolecular cycloaddition reaction is described for the enantioselective synthesis of bicyclic oxazolidines. By choice of the precursor, the products possess a chiral quaternary bridgehead aryl substitution. Also describ

Regio- and Enantioselective Synthesis of Novel Functionalized Pyranopyrrolidines by 1,3-Dipolar Cycloaddition of Carbohydrates

Autor: Bernard Mauze, Celine Cano, George Bashiardes

Publikováno v: ChemInform. 36

A new methodology is described for the rapid enantiomeric synthesis of a novel series of pyranopyrrolidines from readily available and inexpensive carbohydrate compounds. The major feature of the method is a highly selective [3+2] cycloaddition react
