Mr. Saidi et Hr. Khalaji, A TANDEM AMINOALKYLATION OF ALDEHYDES - APPLICATION TO THE SYNTHESIS OF SUBSTITUTED PHENOLS AND NAPHTHOLS, Journal of chemical research. Synopses, (9), 1997, pp. 340-341
Treatment of a protected salicylic aldehyde (2) and 2-hydroxy-1-naphth
aldehyde (6) with (trimethylsilyl)dialkylamines and various nucleophil
es in a 5 M diethyl ether solution of lithium perchlorate gives a vari
ety of N,N-dialkylaminophenols (4) and 1-(N,N-dialkylamino)-2-naphthol
s (8) in short reaction times and in good yields.
