Article abstract of DOI:10.1248/cpb.39.3123

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
