Participants

Reaction Steps

Methane sulphonylchloride (8.07 g; 1.1 eq) was added dropwise over 30 minutes to a stirred solution of 9-hydroxy-non-7-en-2-one (10 g) in dry dichloromethane (60 ml) containing an excess of triethylamine (9.71 g; 1.5 eq), at -10° C. The solution was stirred for a further 20 minutes. The reaction mixture was washed with cold water, cold 5 N hydrochloric acid, cold 5% sodium bicarbonate solution and cold brine then was dried and evaporated in vacuo at <30° to give 9-mesyloxy-non-7-en-2-one (12.7 g) as a deep red oil.
