Yield:101-97-3 100%

Reaction Conditions:

with Novozym 435;acylase I from Aspergillus melleus;amano lipase AK from pseudomonas fluorescens;lipase from wheat germ;papaine in toluene at 40; for 48 h;Mechanism;Enzymatic reaction;

Steps:

4.3. Experimental setup

General procedure: To the solution of acid (1 mmol) in toluene (1 ml), the corresponding dialkyl carbonate (2 mmol) and enzymes (per 4 mg of each enzyme) were added in 5 ml vial. The reaction mixture was stirring for 24 or 48 h at 40 °C in vortex mixture (Heidolph Promax 1020) equipped with incubator (Heidolph Inkubator 1000). After cooling, the mixture was washed with NaHCO3 (3×) and brine (1×). Organic solvent was removed under vacuum to obtain the product 2a-2r.
