Abstract
In the title compound, C16H17NO4, the five-membered lactone ring is tr ans-fused to the cyclohexene ring. The cyclohexene ring exhibits a hal f-chair conformation with the benzamido group in an axial position. Th e gamma-butyrolactone adopts an envelope conformation with the hydroxy methyl substituent in a pseudo-equatorial position. The crystal struct ure is stabilized by two intermolecular hydrogen bonds (O-H ... O and N-H ... O) involving the benzamido and hydroxy groups.
