The preparation of a number of alkyl and alkoxy derivatives of pentacyclo[5.4.0.0(2,6).0(3,10).0(5,9)]undecane-8,11-dione derivatives utilising a cheap, practical, low energy, 'green', single-pass continuous flow photochemical reactor is reported. Their (1)H and (13)C NMR spectra are fully assigned, revealing some general characteristics not previously reported for this class of compound, which should aid the assignment and prediction of the NMR spectra of PCUD derivatives.

We report late-stage ring-opening metathesis (ROM), ring-rearrangement metathesis (RRM), and ring-closing metathesis (RCM) approaches to generate expanded pentacycloundecane (PCUD) cage derivatives. These higher-order intricate polycyclic cage systems are aesthetically pleasing and structurally intriguing. Their assembly maintains molecular symmetry during the entire synthetic sequence.
