Ligand Control of E/Z Selectivity in Nickel-Catalyzed Transfer Hydrogenative Alkyne Semireduction

A nickel-catalyzed transfer hydrogenative alkyne semireduction protocol that can be applied to both internal and terminal alkynes using formic acid and Zn as the terminal reductants has been developed. In the case of internal alkynes, the (E)- or (Z)-olefin isomer can be accessed selectively under the same reaction conditions by judicious inclusion of a triphos ligand.

A study on the Z-selective Horner-Wadsworth-Emmons (HWE) reaction of methyl diarylphosphonoacetates

Experimental and theoretical studies were conducted to explore the Z-selectivities in the Horner-Wadsworth-Emmons (HWE) reaction employing several methyl diarylphosphonoacetates (3, 4, 5 and 6) and aldehydes. The Z-selectivity depended upon the reaction conditions such as the bases, reaction temperature, and the aromatic substituents on the phosphorus atoms but the almost phosphonoacetates used in the present study showed Z-selectivity in the reactions with both aromatic and aliphatic aldehydes. While the phosphonoacetate (3) with bis(2,4-difluorophenyl)phosphono group showed the highest Z-selectivity in all reaction conditions employed, decrease of the selectivity was observed in the case of some phosphonoacetates with diarylphosphono groups. These experimental results and the theoretical studies calculated by AM1 or 3-21G* ab initio methods suggested that the steric effect in the transition states of the addition steps was important rather than the electronic effect. A different aspect of the reaction courses between the Wittig and HWE reactions in the present computational chemistry was also described.

ETUDE DE LA REACTION CHLOROCARBENE-ACETALS DE CETENES. II. STEREOSELECTIVITE DE LA REACTION.

We have studied the stereoselectivity of the addition reaction of chloro and chloromethyl carbenoids with ketene alkylsilyl acetals.The best stereoselectivity was generally observed with the dimethyl tertiobutylsilyloxy group.With the chlorocarbenoid, using an E ketene acetal we obtained in majority (ca. 80percent) an E α,β-ethylenic ester and using a Z ketene acetal we obtained in majority (ca. 70percent) a Z α,β-ethylenic ester.In the case of the chloromethyl carbenoid the two ketene acetal isomers led to the same α-substituted α,β-ethylenic ester (ca. 88percent of selectivity).With the chlorophenylcarbenoid, formation of ca. 90percent of E α phenyl α,β-ethylenic ester is observed.
