[Structure: see text] Pinnatoxins B and C were synthesized from diols (34R)-3b and (34S)-3a, respectively, in a stereochemically controlled manner. Through extensive analysis of the 1H NMR spectra of synthetic PnTXs B and C, the diagnostic NMR signals were first identified to differentiate (34S)- and (34R)-diastereomers and then used to establish the C34 configuration of natural PnTXs B and C as 34S and 34R, respectively. ...[more]
