Yield:60-18-4 81%

Reaction Conditions:

with acetic acid in water at 160; for 0.0833333 h;Microwave irradiation;optical yield given as %ee;

Steps:

7 A typical procedure is shown here:

General procedure: A mixture of 3 (0.8 g, 1.94 mmol) in acetic acid (0.2 M, 9.7 mL) and water (0.2 M; 9.7 mL) was heated to 160 °C in a Biotage Initiator microwave for 5 min. After cooled to rt, the reaction mixture was concentrated in vacuo. Water was added and removed in vacuo (twice) to remove the residual acetic acid. The residual was washed with iPrOH to afford 2 (0.44 g, 98%) as a white solid after drying.
