Abstract
A facile and highly efficient copper- and palladium-free procedure
for the one-pot synthesis of ynones via coupling of sodium carboxylate
salts with alkynes is described. In this method, cross-coupling
of terminal alkynes with a mixture of structurally diverse sodium
carboxylate salts, cyanuric chloride and triethylamine in the presence
of magnesium chloride furnishes the corresponding ynones in good
to excellent yields at room temperature.
Key words
one-pot synthesis - alkyne - cyanuric chloride - sodium carboxylate salt - ynone

26 General procedure for coupling of
alkynes with sodium carboxylate salts using cyanuric chloride: To
a solution of sodium carboxylate salt (3.3 mmol) in anhydrous MeCN
(5 mL), was added TCT (1 mmol) and the reaction mixture was stirred
at r.t. for 10 min. A solution of the appropriate alkyne (3 mmol),
Et3 N (3.3 mmol) and MgCl2 (3.3 mmol) in anhydrous
MeCN (5 mL) was added and the solution was stirred for a further
50-110 min (until TLC indicated completion of the reaction,
see Table
[5 ]
). The solution
was filtered and the solvent was evaporated under vacuum. The remaining
foam was then diluted in CHCl3 (50 mL) and subsequently
washed with H2 O (2 × 50 mL).
The organic layer was dried (Na2 SO4 ) and evaporated.
The crude product was purified by short column chromatography on
silica gel (n -hexane-EtOAc,
20:1).
