Gold-catalyzed addition of carbon nucleophiles to propargyl carboxylates
Amijs, Catelijne H. M.,Lopez-Carrillo, Veronica,Echavarren, Antonio M.
, p. 4021 - 4024 (2007)
Propargyl carboxylates react with 1,3-dicarbonyl compounds and electron-rich arenes in the presence of Au(l) catalysts to give enol carboxylates via α,β-unsaturated Au(l) carbenes or Au(l)-coordinated alienes formed by 1,2- or 1,3-acyl migration, respecti
Yb(OTf)3-catalyzed propargylation and allenylation of 1,3-dicarbonyl derivatives with propargylic alcohols: one-pot synthesis of multi-substituted furocoumarin
Huang, Wen,Wang, Jialiang,Shen, Quansheng,Zhou, Xigeng
, p. 11636 - 11643 (2007)
A highly efficient and mild Lewis acid-catalyzed coupling reaction of 1,3-dicarbonyl compounds with propargylic alcohols has been established. Selective propargylation or allenylation products are obtained depending on the nature of propargylic alcohols.
SnCl2-catalyzed propargylic substitution of propargylic alcohols with carbon and nitrogen nucleophiles
Masuyama, Yoshiro,Hayashi, Miki,Suzuki, Noriyuki
, p. 2914 - 2921 (2013/07/05)
A weak Lewis acid, tin(II) chloride, which is insensitive to water and air, functioned as a catalyst for the propargylic substitution of secondary propargylic alcohols with carbon nucleophiles, such as electron-rich arenes, heteroarenes, and 1,3-dicarbony
Condensation of propargylic alcohols with 1,3-dicarbonyl compounds and 4-hydroxycoumarins in ionic liquids (ILs)
Aridoss, Gopalakrishnan,Laali, Kenneth K.
supporting information; experimental part, p. 6859 - 6864 (2012/02/05)
Propargylic alcohols are activated toward 1,3-diketones by Lewis or Br?nsted acidic ionic liquids (ILs) without an added catalyst, but significantly better conversions are achieved with metallic triflates [in particular Sc(OTf)3 and Ln(OTf)sub
Bronsted acid catalyzed propargylation of 1,3-dicarbonyl derivatives. Synthesis of tetrasubstituted furans
Sanz, Roberto,Miguel, Delia,Martinez, Alberto,Alvarez-Gutierrez, Julia M.,Rodriguez, Felix
, p. 727 - 730 (2007/10/03)
Simple Bronsted acids such as p-toluenesulfonic acid monohydrate (PTS) efficiently catalyze a direct substitution of the hydroxyl group in propargylic alcohols with 1,3-dicarbonyl compounds. Selective propargylation or allenylation is obtained depending o
