The introduction of ortho-substituted groups to the biaryl ring restricts the rotation of substituents linked to the phosphine, resulting in conformational rigidity.
Thus, we will develop catalytic cross-coupling processes proceeding via (1) gold(I) mediated C-H activation of electron poor arenes, (2) oxidation of the catalyst to gold(III) followed by gold(III) mediated C-H activation of electron rich arenes, and (3) C-C bond formation furnishing biaryl compounds.
Many drug substances' pharmaceutical activity is exerted by a structural motif called a biaryl unit.
In his lecture, Suzuki gave an historical perspective of his reaction in the context of progress in boron chemistry, developed the theme of use of organoboron coupling reactions for the synthesis of dienes and biaryls, and, concentrating on work from other laboratories, provided an up-to-date report on the numerous applications of the Suzuki reaction inbioactive molecule and natural product synthesis.
