D− A cycloadditions of 3, 5-dibromo-2-pyrone were investigated with a series of
electronically and sterically distinct dienophiles. Our results showed that it is a highly potent …

An efficient one-pot protocol for the synthesis of multi-substituted 2-pyrone derivatives from
internal alkynes and unactivated alkenes is reported. The methodology involves …

A review with 1811 references about transition metal catalyzed or mediated reactions and
functional group preparations is presented.

3-(Trimethylstannyl)-5-bromo-2-pyrone underwent facile Stille coupling reactions with aryl
halides to produce various 3-substituted 5-bromo-2-pyrones. The resulting 3-aryl-2-pyrone …
