Abstract
Two cis,cis-iridolactones with a natural (S)-configuration at C(1) have been synthetized and their crystal and molecular structures determined by direct methods and refined by least-squares to R 0.109 and 0.064. The heterocyclic ring has a boat conformation which allows the C (8) methyl group to assume an equatorial position.Spectroscopic measurements indicate that this type of geometry is also present in solution.
