چکیده
|
A n-heterocyclic carbene (nhc) catalyzed addition reaction of 3-trimethylsilyl propiolate with aldehydes has been developed. under the catalysis of 2 mol% nhcs,benzaldehyde,furfural,β-naphthaldehyde,meta- and para-substituted aromatic aldehydes reacted with 3-trimethylsilyl propiolate to afford β-acylated mbh adducts in good yield with excellent stereoselectivity. while ortho-substituted benzaldehydes coupled with 3-trimethylsilyl propiolate to give alkynylation products as the sole products under the same reaction conditions. © 2014 king saud university.
