Sonogashira cross-coupling reaction of 3-iodoindazoles with various terminal alkynes: a mild and flexible strategy to design 2-aza tryptamines
摘要:
This paper describes a Sonogashira-type cross-coupling reaction of 3-iodoindazoles various terminal alkynes as a general route to 3-alkynylindazoles. The Coupling reaction is illustrated by the preparation of ne indazolylpropiolic or propargylic derivatives. Scope and limitation of the method are outlined. (C) 2002 Elsevier Science Ltd.
