Abstract:
The NMR solution structure of calyculin A (1) in chloroform exhibits intramolecular interactions, resembling the original crystal structure. In methanol, calyculin A has the hydrogen bonding moieties solvent exposed. Dephosphonocalyculin A in chloroform resembles calyculin A in chloroform and the crystal structure of calyculin A. Dephosphonocalyculin A in methanol resembles calyculin A in methanol.
