Circular Dichroism of Bufadienolides

Croatica Chemica Acta, 1985
With the help of PMO theory a non-empirical sector rule has been derived for the n ~ 1t5* band CD (around 260 nm) of the pentadienolide chromophore of steroidal bufadienolides. The rule was verified by experiment using the preferred conformation for the 2-pyrone side chain found in most of the crystalline bufadienolides investigated by x-ray ...
