In this study, lipase-mediated dynamic kinetic resolution (DKR) of various benzylic amines (1a-g) is presented which is realized in a so far unprecedented fully continuous-flow system. The DKR process applying sol-gel immobilized lipase B from Candida antarctica as biocatalyst, palladium on 3-aminopropyl-functionalized silica as racemization catalyst, isopropyl 2-ethoxyacetate as acylating agent, ammonium formate as hydrogen and nitrogen sources, and 2-methyl-2-butanol as solvent under regulated pressure provided the desired products in moderate to good yields with excellent enantiomeric excesses.

Ternary reaction systems consisting of a carbene , a cyclic ether (THF, THP) and a protic nucleophile (alcohol, water, carboxylic acid, thiol, or amine) give the corresponding three-component coupling products which are produced via ethereal oxonium ylide intermediates.The mechanism leading to the product formation has been studied in which protonation of carbenes is excluded.
