Synthetic Methods for Fluorinated Olefins
Hikaru Yanai,Takeo Taguchi +1 more
TL;DR: In this paper, an overview of recent progress in synthesizing fluoro-olefin compounds and some classical but still valuable synthetic reactions is presented. But the authors do not provide a detailed analysis of the synthesis process.
Journal ArticleDOI
Indium(III) triflate catalyzed tandem azidation/1,3-dipolar cycloaddition reaction of ω,ω-dialkoxyalkyne derivatives with trimethylsilyl azide
Hikaru Yanai,Takeo Taguchi +1 more
TL;DR: Novel tandem azidation/1,3-dipolar cycloaddition reaction using alkynyl acetal derivatives gave bicyclic triazolo-heterocyclic compounds, recognized as chemically modified aza-sugar analogues, in high yields under mild conditions.
Journal ArticleDOI
Tetrakis(trifluoromethanesulfonyl)propane: highly effective Brønsted acid catalyst for vinylogous Mukaiyama–Michael reaction of α,β-enones with silyloxyfurans
TL;DR: 1,1,3,3-Tetrakis(trifluoromethanesulfonyl)propane was found as an excellent Brønsted acid catalyst for the Mukaiyama-Michael reaction of alpha,beta-enones with 2-silyloxyfurans; an excellent yield construction of quaternary carbon centers could be achieved.
Journal ArticleDOI
Highly effective vinylogous Mukaiyama-Michael reaction catalyzed by silyl methide species generated from 1,1,3,3-tetrakis(trifluoromethanesulfonyl)propane.
TL;DR: Silyl methide species in situ generated from 1,1,3,3-tetrakis(trifluoromethanesulfonyl)propane (Tf( 2)CHCH(2)CHTf (2)) performed as an excellent acid catalyst for the vinylogous Mukaiyama-Michael reaction of alpha,beta-unsaturated ketones with 2-silyloxyfurans.
Journal ArticleDOI
An effective method to introduce carbon acid functionality: 2,2-bis(trifluoromethanesulfonyl)ethylation reaction of arenes.
TL;DR: The Tf2CH-CH2 functionality is introduced to a wide range of phenols or phenol ethers ortho to the hydroxy or ether group as mentioned in this paper, and it is used in a variety of applications.
