摘要：
The present invention provides a process for preparing &bgr;-hydroxy-&ggr;-butyrolactone or &bgr;-methyl-&bgr;-hydroxy-&ggr;-butyrolactone represented by the formula (1): wherein R1 is hydrogen or methyl, which entails a) cyanating glycidol or 2-methyl-2,3-epoxypropanol, b) hydrolyzing the product of step a), and c) lactonizing the product of step b).
