Participants

Reaction Steps

(2R,3S)—N-hydroxy-3-(methoxymethyl)-1,4-dioxaspiro[4.5]decane-2-carbimidoyl chloride (35.6 g, 135.0 mmol) was dissolved in Et2O (600 mL) and cooled in an ice bath. Methanesulfonyl chloride (10.49 ml, 135.0 mmol) was added, followed by dropwise addition of triethylamine (18.82 ml, 135.0 mmol). The reaction was stirred for 30 minutes and then filtered and concentrated. The residue was purified on 1 Kg SiO2 (1 to 5% EtOAc in CH2Cl2) to afford (2R,3S)-3-(methoxymethyl)-N-(methylsulfonyloxy)-1,4-dioxaspiro[4.5]decane-2-carbimidoyl chloride (22.6 g, 66.12 mmol, 48.98% yield).
