✦ Synopsis

The title compound, C 19 H 18 O 5 , is a diastereoisomer of crotocaudin, both being isolated from the plants of genus Croton. In isocrotocaudin, the furan moiety makes a dihedral angle with the adjacent lactone of 13.53 (17) . The cyclohexyl ring of the diterpene moiety adopts a chair confirmation. The weak intermolecular C-HÁ Á ÁO hydrogen bonds link the molecules into linear chains along the c axis.
