Directed Zincation or Magnesiation of 2- and 4-Pyrones and Their Derivatives

A regioselective magnesiation of the 2-pyrone scaffold was developed. Magnesiation of this heterocycle by using TMPMgCl·LiCl (TMP = 2,2,6,6-tetramethylpiperidyl) followed by trapping reactions with electrophiles such as aldehydes, allylic bromides, acid c

Gold(I)-catalyzed cycloisomerization of β-alkynylpropiolactones to substituted α-pyrones

Substituted α-pyrones were straightforwardly synthesized in good to excellent yields by a new gold(I)-catalyzed rearrangement of β-alkynylpropiolactones.
