1,2,4‐Triazine compounds were synthesized via two coupled domino strategies employing simple and readily available arylacetaldehydes/arylethyl alcohols as starting materials. The reactions proceed smoothly in one pot with the advantages of high functional groups tolerance, being transition metal‐free, and employing environmentally friendly oxidants such as I2 and IBX, providing access to the desired
and efficient [4 + 2] domino annulation reactions have been developed for the synthesis of 1,2,4-triazine derivatives. The strategies exhibit high performance with moderate to high yields, using easily available materials including ketones, aldehydes, alkynes, secondary alcohols and alkenes, representing a powerful tool for the formation of potentially biologically active derivatives.
