✦ Synopsis

Halochromic Molecules. Synthesis of Substituted 6__H__‐Chromeno[4,3‐b]indolizines and their Aza‐analogues

We have synthesized a series of substituted chromeno[4,3‐b]indolizines and their respective aza‐analogues. Dyes generated from them contain the electrondonating 2‐(2‐hydroxy‐5‐methylphenyl)indolizin‐3‐yl moiety. The 90 MHz FT ^1^H‐NMR spectra of starting and final products supported the postulated structures. Fragmentations in the mass spectra also were consistent with the assumed structures.
