tert-butyl N-(3-hydroxy-2,2-dimethylcyclobutyl)carbamate

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

実験手順: To a solution of tert-butyl (2,2-dimethyl-3-oxocyclobutyl)carbamate (1.0 equiv.) in MeOH (0.1 M) was added sodium borohydride (1.0 equiv.) in small portions at 0° C. After addition, the mixture was stirred at room temperature for 2 h, then the mixture was quenched with acetone. The solvent was removed under vacuum, the residue was passed through a short silica gel column chromatography (40% ethyl acetate in petroleum ether) to afford the crude title product (85% yield), which was used for the next step without further purification. MS (ESI) m/z 216.2 [M+H]+. After addition the mixture was quenched with acetone The solvent was removed under vacuum
