Synthesis of azamacrocycles via a Mitsunobu reaction
摘要:
Reaction of pernosylated diethylenetriamine and 2-substituted propane-1,3-diols in dry THF in the presence of triphenylphosphine and diisopropyl azodicarboxylate gives the corresponding protected 9-substituted 1,4,7-triazacyclodecaries. The Mitstinobu reaction was also used in the preparation of 3-substituted 1,5,9-triazacyclododecanes and macrocyclic pyridine derivatives. (c) 2005 Elsevier Ltd. All rights reserved.
