Herein, a chemoselective cascade addition reaction is reported, which starts from
1,2,3-triazines and thiols to access several different α-substituted β-thio enals
and their derivatives in a green and efficient synthesis. In terms of applications,
readily available substrates, diversity of products, and mild reaction system make
this strategy highly attractive.
Key words
1,2,3-triazines - thiols - cascade reaction - thiolation - enals
