✦ Synopsis

The bicyclo[53,0]decane containing 23, which should serve as a precursor to a variety of guaianolides and pseudoguaianolides has been constructed in 5 steps and 36% overall yield via a furan terminated cationic cyclization.

Bicyclo[5.3.0]decane subunits occur in nature as integral parts of complex bioactive natural products such as guaianolides 2 and pseudoguaianolides 2. These functionally and stereochemically complex compounds have attracted
