A biomass-involved, one-pot, two-step protocol for the synthesis of N-substituted 3,4-dihydro-2H-1,4-benzoxazines has been developed. A wide range of new compounds have been efficiently synthesized in moderate to excellent yields via the three-component consecutive reactions between methyl 3-dehydroshikimiate (3-MDHS), amines and 1,2-dichloroalkanes in short reaction times under microwave conditions.

family of secondaryarylamines, including diarylamines and arylalkylamines have been synthesized in good yields starting from the renewable and biomass-based feedstock (−)-shikimic acid (1). The tandem cross-coupling and aromatization reactions between primary amines and the intermediate (−)-methyl-3-dehydroshikimate (3) are crucial for realizing this strategy. The application of arylamines and alkylamines
