چکیده

A novel and efficient approach to 3-allyl-chromones from alkynones and allylic alcohols via a tandem Michael addition-Claisen rearrangement-O-arylation reaction has been developed. Diversely structural 3-allyl-chromones were afforded in up to 93% yield for 24 examples. This synthetic strategy is regiospecific, highly efficient, environment friendly and metal-free.

Transition‐Metal‐Free Borylation of Allylic and Propargylic Alcohols

The base-catalyzed allylic borylation of tertiary allylic alcohols allows the synthesis of 1,1-disubstituted allyl boronates, in moderate to high yield. The unexpected tandem performance of the Lewis acid-base adduct, [Hbase](+) [MeO-B2 pin2 ](-) favored the formation of 1,2,3-triborylated species from the tertiary allylic alcohols and 1-propargylic cyclohexanol at 90 °C.

A Tandem Scalable Microwave-Assisted Williamson Alkyl Aryl Ether Synthesis under Mild Conditions

An efficient tandem synthesis of alkyl aryl ethers, including valuable building blocks of dialdehyde and dinitro groups under microwave irradiation and solvent free conditions on potassium carbonate as a mild solid base has been developed. A series of alkyl aryl ethers were obtained from alcohols in excellent yields by following the Williamson ether synthesis protocol under practical mild condi...

Synthesis of highly substituted allylic alcohols by a regio- and stereo-defined CuCl-mediated carbometallation reaction of 3-aryl-substituted secondary propargylic alcohols with Grignard reagents.

A highly regio- and stereoselective CuCl-mediated carbometallation reaction of 3-aryl-substituted secondary propargylic alcohols with alkyl, aryl, vinyl or allyl Grignard reagents for the synthesis of fully-substituted allylic alcohols was developed. The R(2) group from the Grignard reagent was successfully introduced to the 2-position of the propargylic alcohols due to the chelation of metal a...

[Development of unprotected syntheses in aqueous media].

Introduction of carbon side chain at C(3)-position of indole ring was accomplished by using Pd-catalyzed allylation and vinylation. The selective vinylation at C(3)-position of 4-bromoindole was applied to the synthesis of optically active 4-bromotryptophan derivatives, which was used as a starting material for the synthesis of several optically active ergot alkaloids, which were clavicipitic a...

Allylic alcohols as synthetic enolate equivalents: isomerisation and tandem reactions catalysed by transition metal complexes.

Allylic alcohols can be isomerised into carbonyl compounds by transition metal complexes. In the last few years, catalyst design and development have resulted in highly efficient isomerisations under mild reaction conditions, including enantioselective versions. In addition, the isomerisation of allylic alcohols has been combined with C-C bond forming reactions when electrophiles such as aldehy...
