An enzyme acylation catalyst and a heterogeneous Brønsted acid as an isomerization/racemization catalyst enables a migratory dynamic kinetic resolution of readily available carbocyclic tertiary carbinols to yield allylic esters in high yield with excellent stereoselectivity. An easy-to-use teabag setup combining resin-bound catalysts, a biphasic isooctane-water solvent system, and a highly lipophilic acyl donor efficiently suppresses side reactions.
