T. Koike et al., Aminoacrylates. II. An efficient synthesis of alpha-pyridones by heterocyclic annelation reactions of magnesium amides derived from sec-aminoacrylates with methyl propiolate, CHEM PHARM, 47(1), 1999, pp. 128-130
The reactions of magnesium amides 4 derived from sec-aminoacrylates 3 and e
thylmagnesium bromide with methyl propiolate (2) afforded alpha-pyridones.
This provides an efficient heterocyclic annelation reaction.
