Asymmetric synthesis of permethric acid. stereochemistry of chiral copper carbenoid reaction

Abstract The most effective optical isomer (1 R - cis ) of permethric acid ( 2 , R = H), a potent intermediate in the production of synthetic pyrethroid, was enantioselectively prepared.

Continuous Hydrolysis of Lactose in Skim Milk and Acid Whey by Immobilized Lactase of Aspergillus Oryzae

We report here the development of a stable immobilized lactase to hydrolyze lactoses in both skim milk and acid whey. Aspergillus oryzae lactase was used. This fungal lactase has good thermal stability and effective activity in the pH ranges of both milk and acid whey (1,2).
