title: The pseudocalanolides: structure revision of calanolides C and D.
abstract: Nmr spectra of synthetic structures corresponding to those initially reported for natural compounds calanolide C [1] and calanolide D [2] showed some subtle differences from those of the natural products. Further analysis has resulted in revision of the structures of the natural compounds, now renamed pseudocalanolides C [3] and D [4]. The absolute stereochemistry of pseudocalanolide C was established as [6S, 7S, 8R] using the modified Mosher's method.
