Synthesis of (E)-1-bromo-3-ethyl-3-pentene

The synthesis of (E)-1-bromo-3-ethyl-3-pentene 1 is described in which the (E)-stereochemistry of the alkene is set up via a diastereoselective glyoxylate ene reaction.

Enantioselective distribution of amino-alcohols in a liquid-liquid two-phase system containing dialkyl L-tartrate and boric acid

Racemic amino-alcohols such as pindolol, propranolol, alprenolol and bucumolol enantiomers exhibited different distribution behaviors in a two-phase system consisting of a chloroform solution of didodecyl L-tartrate and an aqueous solution of boric acid. It seemed that a borate complex of the 1,2-diol group of the tartrate and the amino-alcohol was formed in the system. In the case of pindolol, one enantiomer was preferentially extracted into the organic phase (x 2.20) at equilibrium.

A CONVENIENT METHOD FOR ENZYMATIC BENZYL-ALKYL TRANSESTERIFICATION UNDER MILD NEUTRAL CONDITIONS
