Sydnone C-4 heteroarylation with an indolizine ring via Chichibabin indolizine synthesis
نویسندگان
چکیده
The synthesis of sydnones heteroarylated at C-4 with an indolizine was achieved by Chichibabin (Tschitschibabin) indolizine synthesis starting from the corresponding sydnone-N-pyridinium bromides. The latter compounds were also transformed to sydnone-indolizines connected through a keto group at the C-4 position by refluxing them in 1,2-epoxybutane with an activated alkyne. The structures of the new compounds were assigned by FTIR, NMR spectroscopy and X-ray analysis.

One-pot Synthesis of Polysubstituted Indolizine Derivatives
An efficient approach to the synthesis of 1,2,3-trisubstituted indolizines is described via one-pot reactions of pyridine and dialkyl acetylendicarboxylate in the presence of ethyl 2-chloroacetoacetate in MeOH at room temperature. The corresponding 1, 2, 3-trisubstituted indolizines may be useful building blocks for the construction of complex indolizine derivatives.
