Abstract
The structure (III) reported by Lappin (2) for the diadducts formed by the reaction of methyl propiolate with 2-aminopyridines has been found to be incorrect. The correct structure (IV) has been proven by spectral studies and cyclisation to compound VII. In two cases new compounds having structures of the type (III) have been isolated. N.M.R. data are reported for all products.
