Abstract

1-Aminopyridinium ylides are important synthetic intermediates as they undergo 1,3 dipolar cycloaddition reactions with a variety of dipolarophiles to yield indolizine derivatives, which have been used in the synthesis of alkaloids, 1., and and undergo photoisomerization to yield 1(1H),2-diazepine derivatives. 2 The chemistry of 1-aminopyridinium ylides is underdeveloped due to the lack of availability of methods for their synthesis. Although these compounds can be prepared ...
