Sb. Sobolov et al., SELECTIVE N-ALKYLATION OF PYRROLOPYRIMIDINES AND INDOLES BY TRANSFER OF ACTIVATION, Tetrahedron letters, 39(32), 1998, pp. 5685-5688
The benzene sulfonyl group is used as a ''transfer of activation'' rea
gent to alkylate selectively the NH of both pyrrolopyrimidines and 5-a
minoindoles substituted on thienopyrimidines. A variety of primary and
secondary alcohols are utilized as alkylating substrates. (C) 1998 El
