A series of fifteen 2-tetrazolylmethyl-isoindolin-1-one linked-type bis-heterocycles were synthesized in 10-76% yields under mild conditions via a one-pot Ugi-azide/(Nacylation/-Diels-Alder)/dehydration process from furan-2-ylmethanamine, aldehydes, isocyanides, azidotrimethylsilane, and maleic anhydride. Density functional theory calculations were performed using the polarizable continuum model (toluene)-M06-2X-D3/6-311+G(d)//M06-2X-D3/6-31G(d) level of theory to obtain the full energy profile when investigating over eight possible pathways. An anthracene-containing analogue displayed a distribution of its highest occupied molecular orbital-lowest unoccupied molecular orbital throughout both cyclic moieties.
