For multi-substituted 7-deazapurine derivatives synthesized 2,6-dichloro-8-iodo-7-deazapurine

摘要

PROBLEM TO BE SOLVED: To overcome many times and labors needed for synthesizing various polysubstituted 7-deazapurine derivatives which is expected usefulness or the like as pharmaceutical because they are conventionally synthesized through several synthetic routes depending on kinds and positions of substituents.;SOLUTION: Used is 2,6-dichloro-8-iodo-7-deazapurine represented by the following formula (1) available as a key intermediate of polysubstituted 7-deazapurine derivatives. Predetermined substituents can be introduced to 8-, m6- and 2-positions respectively in this order, therefor it is useful as an intermediate for synthesizing targeted polysubstituted 7-deazapurine derivative.;SELECTED DRAWING: None;COPYRIGHT: (C)2016,JPO&INPIT
