Novel catalyst system for hydrostannation of alkynes

A catalyst system was developed for the highly regio-and stereoselective hydrostannation of a range of alkynes with tributylstannane under mild conditions. The active catalytic species was generated from a stable diruthenium complex by illuminating household fluorescent light (30 W) at room temperature.

Regioselective synthesis of multisubstituted benzenes by palladium-catalyzed intermolecular reaction of β-iodo-β-silylstyrenes with alkynes

The Pd-catalyzed reaction between β-iodo-β-silylstyrenes and terminal alkynes in i-Pr2NEt gave 1,2,3,5-tetrasubstituted benzenes with complete regioselection. The use of certain silylacetylenes as alkynes enabled efficient synthesis of 1,3,5-trissilyl-2-arylbenzenes, which could be transformed into other multisubstituted benzenes by displacement of the silyl groups.

A facile one-pot stereoselective synthesis of (Z)-α-Acyl- αβ-Unsaturated esters from alkynyl esters and aryl acyl chlorides

(Z)-α-Acyl-αβ-Unsaturated esters can be stereoselectively synthesised in one pot under mild conditions and in good yields by the palladium-catalysed hydrostannylation of alkynyl esters in benzene, followed by the Stille crosscoupling with aryl acyl chlorides using CuI as co-catalyst.

Novel stereoselective synthesis of (Z)-α,β-unsaturated esters by hydrostannylation-Stille tandem reaction of alkynyl esters with aryl iodides

(Z)-α,β-Unsaturated esters can be stereoselectively synthesised in one pot under mild conditions and in good yields, by the hydrostannylation of alkynyl esters followed by Stille cross-coupling with aryl iodides.

Synthesis of α-stannyl α,β-unsaturated carboxylic esters

A synthetic method for the preparation of α-stannyl α,β-unsaturated esters is described.The lithium enolate derived from tert-butyl α-(tri-n-butylstannyl)-α-(trimethylsilyl)acetate reacts with aldehydes to give moderate to good yields of α-stannylated products.The method is not applicable to enolizable ketones.

Palladium-catalyzed reaction between aryl or alkenyl halides and (1-carbalkoxy-1-alkenyl)zinc iodides. A new class of unmasked β-substituted acrylate α-anion equivalents

Unmasked β-substituted acrylate α-anion equivalents have been directly and very efficiently prepared by insertion of zinc metal into the carbon-iodine bonds of alkyl (E)- or (Z)-2-iodo-2-alkenoates, (E)- or (Z)-(4), respectively.The stereoisomeric composi
