Regio- and Enantio-Selective Photoreactions of Cyclohex-2-Enone, Coumarin and Acrylanilide as Inclusion Complexes with Optically Active Host Compounds
摘要:
Regio- and enantio-selective photodimerization reactions of cyclohex-2-enone (4) and coumarin (7), and enantioselective photocyclization of acrylanilides (12, 16, 18, and 20) in inclusion crystal with optically active host compounds (1, 2, and 3) are reported. X-ray structure studies of the inclusion crystal are also reported.
of N-arylacrylamides with high 5-exo-trig selectivity through robust proton-coupled electrontransfer (PCET). This mild hydroarylation protocol provides a straightforward entry to structurally valuable oxindoles and complements previously established 6-endo-trig cyclization by photochemical triplet energy transfer (TET).
