Abstract
A series of trans/trans and cis/cis fused-bis tetrahydrofuran compounds have been obtained stereoselectively in high yields via a one-pot operation involving the intramolecular haloetherification of (Z,Z)-diene diol 19a and (E,E)-diene disilylether 19d, respectively. This method was subsequently applied to the biomimetic-type synthesis of (±)- and (-)-aplysiallene. The inhibitory activities of these compounds and their bromodiene isomers toward Na(+)/K(+) ATPase were determined in vitro, and gave IC50 values of approximately 15 μM in all cases.
