Selective N-alkylation of pyrrolopyrimidines and indoles by “transfer of activation”
摘要:
The benzene sulfonyl group is used as a "transfer of activation" reagent to alkylate selectively the NH of both pyrrolopyrimidines and 5-aminoindoles substituted on thienopyrimidines. A variety of primary and secondary alcohols are utilized as alkylating substrates. (C) 1998 Elsevier Science Ltd. Ail rights reserved.
The present invention relates to heterocyclic ring-fused pyrimidine derivatives of formula (I) or stereoisomers, pharmaceutically acceptable salts or prodrugs thereof, wherein Z and Y are as defined in the specification.
