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/(N-acylation/exo-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.
