Recent developments on microwave-assisted organic synthesis of nitrogen- and oxygen-containing preferred heterocyclic scaffolds

“…Zhao and co-workers developed an environmentally friendly and efficient microwave-promoted multicomponent reaction involving isatins, a-amino acids, and 1,4-dihydro-1,4-epoxynaphthalene. 180 Within a remarkably short time of 15 min, the reaction produced oxygen-bridged spirooxindoles in goodto-excellent yields. Notably, the 1,3-dipolar cycloaddition process exhibited compatibility with various primary amino acids and showcased high efficiency due to its rapid reaction time (Scheme 107).…”
