Naphthalen-1(2H)-one → 1-Tetralol, (S)-

Washed phaseolus aureus L (green grams) 50 g. were taken into a conical flask and allowed to soak in deionised water (400 ml) for a period of 24 hr. 1-naphthalenone (0.500 g; 0.0034 moles) III was added to the soaked phaseolus aureus L (green grams) in the above water, covered and allowed to shake for 46 hr at 15–20° C. Then the green grams were filtered off and washed with deionised water (3×100 ml). The combined filtrate was extracted with chloroform (3×500 ml). The chloroform layer was dried and the crude product obtained (480 mg). Pure (1S)-1,2,3,4-tetrahydro-1-naphthalenol (IV) was obtained after column chromatography with silica gel using chloroform as eluent.
