Oh, Hyeonji published the artcileSynthesis of Bicyclic N-Heterocycles via Photoredox Cycloaddition of Imino-Alkynes and Imino-Alkenes, HPLC of Formula: 151-10-0, the main research area is pyrrolizidinone preparation diastereoselective density functional theory; imino alkyne photoredox cycloaddition photocatalyst; dihydro oxazine preparation diastereoselective density functional theory; alkene imino photoredox cycloaddition photocatalyst.
This redox-neutral reaction involves formal imine-alkyne metathesis followed by redox-mediated annulation with concomitant rearrangement. The synthesis of pyrrolizidinones I [n = 1,2; R1 = H, Me; R2 = H, Me, Ph, C(O)OMe; R3 = H, Me, C(O)OMe; R2R3 = -(CH2)5-; R4 = 4-chlorophenyl, pyrimidin-5-yl, isoquinolin-4-yl, etc.; R5 = i-Pr, Et, Bn, t-Bu; R6 = i-Pr, Et, Bn, t-Bu] based on intramol. imine-alkynes II [2+2] cycloaddition under visible light photocatalysis have been reported. In contrast, the use of imino-alkenes III [X = CH2, O, S(O)2, TsN; R7 = H, Me; R8 = H, Me, Ph, etc.; R7R8 = -(CH2)5-; R9 = H, Me] provides dihydro-1,4-oxazines IV via an alternative [4+2] cycloaddition pathway. The proposed reaction mechanisms were supported by control experiments and DFT calculations
