A total of 41 analogues were prepared in isolated yields of 17–99 %. This process was highly tolerant of aliphatic, aromatic, heterocyclic, and acyclic aldehydes, but furan, pyrrole, and thiophene aldehyde reactivity correlated with propensity towards electrophilic addition and/or Diels–Alder addition. As a result, thiophene afforded high yields (80 %) whereas pyrrole carboxaldehyde failed to react. With simple cinnamaldehydes, and in the SbCl₃-mediated reaction, and with α,β-unsaturated aldehydes the equivalent quinazolin-4(3H)-ones, and not the 2,3-dihydroquinazolin-4(1H)-ones, was favoured.]]> Thu 05 Aug 2021 11:45:40 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47451 Fri 20 Jan 2023 16:33:46 AEDT ]]>
