Stereoselective Synthesis of Rubrenoic and nor‐Rubrenoic acids
摘要:
The total stereoselective synthesis of (Z)-rubrenoic I (1a), (Z)-nor-rubrenoic I (17a), (E)-rubrenoic III (3b), and nor-(E)-rubrenoic III (30b) acids was achieved using Suzuki and Stille cross-coupling reactions from readily available starting materials.

An unprecedented exploration of tertiary amines as alkyl radical equivalents for cross-coupling with aromatic alkynes to access allylarenes has been achieved by a P/N heteroleptic Cu(I)-based photosensitizer under photoredox catalysis conditions. Mechanistic studies reveal that the reaction might undergo radical addition of in situ-generated α-amino radical intermediates to alkynes followed by 1,5-hydrogen
