Synthesis of Programmable Tetra-ortho-Substituted Biaryl Compounds Using Diels−Alder Cycloadditions/Cycloreversions of Disubstituted Alkynyl Stannanes
摘要:
Orthogonally functionalized, programmable biaryl templates have been synthesized utilizing aryl acetylenic stannanes and oxygenated dienes in a cycloaddition/cycloreversion strategy. Sequential functionalization of each of the four ortho positions has been demonstrated. Subsequent resolution of a representative anilino phenol has been accomplished. Additionally, a highly active anhydrous, boroxine-based Suzuki coupling protocol has been developed for conversion of unreactive aryl chlorides.
