Resumo
Herein, we present a robust and eco-friendly dynamic kinetic resolution (DKR) protocol for secondary alcohols using a combined heterogeneous catalytic CAL−B/VOSO4 system at 50 °C in the relatively green solvent heptane. This catalytic system is active and chemo- and enantioselective for up to 5 cycles. A set of 13 aromatic and heteroaromatic secondary alcohols were evaluated to determine the substrate scope. The performance of the combined CAL−B/VOSO4 system was improved by employing a low-cost, homemade Teflon tube to compartmentalize the catalysts in one-pot conditions, making this system for up to 8 reaction cycles.
