资源简介：
A mild
three-component synthetic approach to versatile 2-amino-1,4-dihydropyridines
from terminal alkynes, sulfonyl azides, and N-sulfonyl-1-aza-1,3-butadienes
was successfully developed and relied on the in situ generation of
metalated ynamide intermediates Ib to achieve a formal
inverse electron-demand hetero-Diels–Alder reaction. Experimental
results suggest that alkali metal cations (Li+ and Cs+ ions) might play a critical role to achieve the cycloaddition
process.
