DMP-mediated one-pot oxidative olefination of silyl ethers
Deng, Guisheng,Xu, Baihua,Liu, Chunyu
, p. 5818 - 5821 (2005)
Silyl ethers of arylic, allylic, propargylic and unactivated alcohols could be deprotected and oxidized with Dess-Martin periodinane, and the resulting aldehydes could be directly converted to the corresponding α,β- unsaturated esters in one pot with stabilized phosphoranes. Good selectivities were achieved upon a variety of protecting groups of alcohol by using this method. Other advantages of the protocol included simplicity of operations and high efficiency, as well as good to excellent yields.
Rhodium-catalyzed decarboxylative and dehydrogenative coupling of maleic acids with alkynes and alkenes
Itoh, Masaki,Shimizu, Masaki,Hirano, Koji,Satoh, Tetsuya,Miura, Masahiro
, p. 11427 - 11432 (2013/12/04)
The dehydrogenative coupling of maleic acids with alkynes proceeds smoothly accompanied by decarboxylation under rhodium catalysis to produce variously substituted α-pyrone derivatives. The catalyst system is also applicable to the coupling with 1,3-diyne
Ni-catalyzed homocoupling of 3-halopropenoates in the presence of water: Formation of hexenedioates
Kotora, Martin,Matsumura, Hiroshi,Takahashi, Tamotsu
, p. 236 - 237 (2007/10/03)
Homocoupling of (Z)-3-halopropenoates using a catalytic amount of NiCl2 and Zn in the presence of water in pyridine afforded a mixture of (Z)- and (E)-3-hexenedioates.
