Procedure: In a 500 ml round bottomed flask equipped with thermometer and a magnetic stirrer and an ice bath 6.04 g (1R,2R)-(−)-1,2-cyclohexanediamino-N,N′-bis-(3,5-di-t-butylsalicylidene) cobalt (II) (10 mmol; Strem Chemicals) and 260.38 g rac tert-butyl glycidyl ether (2000 mmol) and 2.40 g acetic acid (40 mmol) and 20 ml THF (tetrahydrofurane) were cooled under stirring to 0° C. and 19.82 g deionized water (1100 mmol) were added all at once. The dark red reaction mixture was stirred under an air atmosphere for 0.5 h at 0° C. and for 23 h at RT. Vacuum distillation over a column filled with “Fenske” glass rings (20×2 cm column; “Fenske” glass rings Ø≅4 mm) afforded 113.2 g (43.5%) (S)-tert-butyl glycidyl ether (S)-1 as colorless liquid, b.p. 84-86° C./100 mbar. were cooled The dark red reaction mixture was stirred under an air atmosphere for 0.5 h at 0° C. and for 23 h at RT Vacuum distillation over a column filled with “Fenske” glass rings (20×2 cm column; “Fenske” glass rings Ø≅4 mm)
