5061-21-2, General procedure: To a stirred mixture of thiols 12a-12k (100 mmol) and K2CO3(27.64 g, 200 mmol) in DMF (120 mL) at room temperaturewas added alpha-bromobutyrolactone (10, 14.85 g, 90 mmol), andthe resulting mixture was stirred at room temperature until thecompletion of reaction as indicated by TLC analysis (typicallywithin 12 h).The reaction mixture was poured into ice-water (400 mL),and the mixture thus obtained was extracted with CH2Cl2 (3 ¡Á100 mL). The combined extracts were washed successively with10% aqueous Na2CO3 (2 ¡Á 100 mL) and 5% brine (3 ¡Á 100 mL),dried over anhydrous Na2SO4 and evaporated on a rotary evaporator to aord a residue, which was purifed by columnchromatography to yield 13a-13k after trituration withEtOAc/n-hexane if the product was a solid.
5061-21-2 2-Bromo-4-butanolide 95463, aTetrahydrofurans compound, is more and more widely used in various fields.
