Les 2-amino-3-cyanothiophènes, précurseurs de théno[2,3-b]pyridines
Written by sctunisie no commentsA convenient preparation of 4-amino-6-ethoxythieno[2,3-b] pyridines is reported. They are prepared by intramolecular cyclization reaction between the corresponding iminoethers derived from 2-amino-3-cyanothiophenes and organomagnesiens.
