Reaction Steps

Sodium 2-propoxide (0.38 ml of 0.1M solution in 2-propanol) was charged to the catalyst solution followed by the α-tetralone (0.5 ml, 3.76 mmol). The mixture was stirred under vacuum (80 mmHg) at 35° C. for 2 h, after the first hour the flask was back filled with nitrogen and sufficient 2-propanol charged to compensate for the volume removed by distillation. This gave (R)-1-tetralol Yield 98.4%, ee 95.7%. The turnover number, integrated over 1 h, was 185 h−1
