2,3-Diarylcyclopropenones react smoothly with pyridine and substituted pyridines in a variety of solvents to produce 1- and/or 3-indolizinols.The regioisomeric indolizines were characterized by X-ray crystallography of their acetate derivatives.The synthesis and spectroscopic properties of a number of indolizinols and their ester derivatives are described.
Oxoindolizine and oxoindolizinium compounds useful as dyes
-
, (2008/06/13)
Oxoindolizine and oxoindolizinium dyes are novel compounds useful in imaging, such as laser recording and reading. These dyes are formed by (1) the reaction of a cyclopropenone and a pyridine compound, (2) by reaction of (a) color-forming couplers with (b
