A mild and effective iodination method using iodine in the presence of bis-(trifluoroacetoxy)iodobenzene
Benhida, Rachid,Blanchard, Pierre,Fourrey, Jean-Louis
, p. 6849 - 6852 (1998)
Herein is described a mild and effective iodination method using bis(trifluoroacetoxy)iodobenzene iodine as reagent to be applied to electron deficient heterocyclic systems (protected indoles coumarin...). Moreover, sensitive protecting groups such as acetyl and tert butyldimethylsilyl were found to be stable under the new iodination reaction conditions.
Synthesis of α-iodo-α,β-unsaturated ketones by the reaction of α- silyl-α,β-unsaturated ketones with ICl or ICIl-AlCl3
Alimardanov, Asaf,Negishi, Ei-ichi
, p. 3839 - 3842 (1999)
Treatment of α-silyl-α,β-unsaturated enones, readily preparable as regio- and stereodefined compounds in high yields, with either 2 equiv, of ICl or one equiv, each of ICl and AlCl3 provides the corresponding α-iodo- α,β-unsaturated enones in h
A convenient protocol for the α-iodination of α,β- unsaturated carbonyl compounds with I2 in an aqueous medium
Krafft, Marie E.,Cran, John W.
, p. 1263 - 1266 (2005)
A variety of cyclic and acyclic α,β-unsaturated carbonyl compounds undergo α-iodination exclusively, in high yields, with I 2, in aqueous THF catalyzed by DMAP and quinuclidine.
Stereoselective preparation of phosphine oxides via a 2,3-sigmatropic shift of allylic diphenylphosphinites
Demay, Stephane,Harms, Klaus,Knochel, Paul
, p. 4981 - 4984 (1999)
The thermic rearrangement of various chiral or racemic allylic diphenylphosphinites to allylic phosphine oxides has been applied for the preparation of several chiral diphosphine oxides of interest for asymmetric catalysis.
Axially chiral aryl olefin compound and synthesis method thereof
-
Paragraph 0025; 0026, (2018/10/11)
The invention relates to the technical field of chemical synthesis, and provides an axially chiral aryl olefin compound and a synthesis method thereof in order to solve the problems of low rotationalenergy barrier, easy racemization and difficult reaction control in the synthesis process of the axially chiral aryl olefin compound. Aryl carbon-hydrogen bonds are directly asymmetrically alkenylatedunder the catalysis of a chiral palladium complex to obtain the axially chiral aryl olefin compound. The above reaction can be completed in an air atmosphere, so the method has the advantages of simplicity in operation, and convenience in post-treatment.
