A highly efficient N-heterocyclic carbene (NHC) catalyzed formal [3+4] cycloaddition reaction of γ-chloroenal with iminoquinones has been developed, producing 4-aminobenzoheptenolactone derivatives in good yields. In order to explore the role of nitroheterocyclic carbene in the site selectivity of the reaction, a theoretical study was carried out using density functional theory. The study showed that the deformation force was the main reason for the difference in site selection.

Key words: N-heterocyclic carbene (NHC), organocatalysis, [4+3] cycloaddition, site selectivity, 4-aminobenzoheptenolactone
