Synthesis of 3-hetaryl-1H-isochromen-1-ones based on 3-(2-bromoacetyl)-1H- isochromen-1-one
Shablykina,Shablykin,Ishchenko,Voronaya,Khilya
, p. 1621 - 1627 (2013/06/27)
A preparative method was developed for the synthesis of 3-(2-bromoacetyl)-1H-isochromen-1-one. Its heterocyclization to 3-(2-R-thiazol-4-yl)-, (3-quinoxalin-2-yl)-, and 3-(imidazo[1,2-a]pyridin-2-yl)- 1H-isochromen-1-ones was studied.
