Regio- and Diastereoselective Organo-Zinc-Promoted Arylation of trans-2,3-Diaryloxiranes by Arylboronic Acids: Stereoselective Access to trans-2,3-Diphenyl-2,3-dihydrobenzofuran

ortho-Oxo substituted trans 2,3-diaryloxiranes were regio- and stereoselectively arylated by arylzinc reagents, obtained from the corresponding boronic acids by B–Zn exchange. The reaction was quite general, irrespective to the aryl nucleophile and proceeded via a ring opening at the α-carbon with respect to the substituted aryl ring. The stereoselectivity was from high to complete toward the alcohol resulted from retention of configuration at the electrophilic carbon. The method allowed a direct and high yielding access to trans 2,3-diphenyl-2,3-dihydrobenzofuran, which is a key structural motif in resveratrol dimers as viniferins. The use of enantioenriched starting diaryloxiranes resulted in no loss of stereochemical integrity in the final trans 2,3-dihydrobenzofuran, which was characterized for the first time in enantioenriched form.

A regioselective lithiation of ortho-cresols using the bis(dimethylamino)phosphoryl group as a directing group: General synthesis of 2,3-dihydrobenzo[b]furans including naturally occurring neolignans

A general synthetic method was developed for 2-aryl-2,3-dihydrobenzo[b]furans via regioselective lithiation of ortho-tolyl tetramethylphosphorodiamidates followed by addition of aromatic aldehydes as a key step. ortho-Tolyl tetramethylphosphorodiamidates
