Versuchsvorschrift
Neat potassium methoxide (133 mg, 1.893 mmol) was added to a solution of methyl 2-(acetylthio)-6-bromohexanoate (536 mg, 1.893 mmol) in an. THF (18 mL) and the mixture was stirred at rt for 2 days under nitrogen. The crude isolate was purified by silica gel FCC (DCM) to afford methyl tetrahydro-2H-thiopyran-2-carboxylate as a clear oil which was saponified (1N NaOH, MeOH-THF) to afford Cap P-38.
