2,5-Dimethyl-3(2H)-furanone → HCID 21875048, compound

Participants

Reaction Steps

2,5-Dimethyl-3(3H)-furanone (2.00 g, 17.8 mmol) was dissolved in methylene chloride (180 mL). TEA (7.43 mL, 53.5 mmol) was added followed by TBSOTf (4.92 mL, 21.4 mmol) at 25° C. After 1 h, the reaction was concentrated in vacuo and the resulting slurry was run through a silica gel column conditioned with 3% TEA in hexanes. The product was eluted with 3% TEA/hexanes to give 3.6 g (89%) of compound 222A as an orange oil which was used directly in subsequent reactions.
