tert-butyl 4-oxocyclohexane-1-carboxylate

反応条件: temp:0.00; pressure:0.00; stir:

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a flask containing THF (82 mL) was added isopropylmagnesium chloride/lithium chloride (1.2 M in THF, 37.7 mL, 45 mmol). A solution of thiazole (3.5 g, 41 mmol) in THF (20 mL) was added slowly. The reaction was stirred for one hour. A solution of tert-butyl 4-oxocyclohexanecarboxylate (12.23 g, 62 mmol) in THF (20 mL) was added and the reaction was stirred for 3 hours. The reaction was then quenched slowly with saturated ammonium chloride and diluted with ethyl acetate. The organic layer was separated, dried over magnesium sulfate, filtered and concentrated. Flash chromatography was used for purification to yield tert-butyl 4-hydroxy-4-(1,3-thiazol-2-yl)cyclohexanecarboxylate (9.25 g, 33 mmol, 79% yield). MS ESI: [M+H]+ m/z 284.1. the reaction was stirred for 3 hours The reaction was then quenched slowly with saturated ammonium chloride diluted with ethyl acetate The organic layer was separated dried over magnesium sulfate filtered concentrated Flash chromatography was used for purification
