Hydroxytetraphenylenes as Chiral Ligands: Application to Asymmetric Darzens Reaction of Diazoacetamide with Aldehydes

Hydroxytetraphenylenes with rigid conformations are potential candidates for employment as chiral ligands in asymmetric synthesis. Highly diastereo- and enantioselective Darzens reactions between aldehydes and diazo-N,N-dimethylacetamide were found to be catalyzed by a chiral titanium complex formed in situ from Ti(O i Pr)4 and chiral 1,16-dihydroxytetraphenylene, leading to the formation of cis-glycidic amides in moderate to high yields with excellent enantiomeric purities (40-99% yield, up to 99% ee).

A Suzuki coupling based route to 2,2′-bis(2-indenyl)biphenyl derivatives

Because of the promising performance in olefin polymerization of 2,2′-bis(2-indenyldiyl)biphenyl zirconium dichloride, we developed a new and broadly applicable route to 2,2′-bis(2-indenyl)biphenyl derivatives. Reaction of the known 2,2′-diiodobiphenyl (26) with the new 2-indenyl boronic acid (23) did not result in the desired 2,2′-bis(2-indenyl)biphenyl (10); instead an isomer thereof, (spiro-1,1-(2,2′-biphenyl)-2-(2-indenyl)indane) (27), was obtained. It was found that compound 10 could be made via a palladium-catalyzed reaction of 2,2-biphenyldiboronic acid (31) with 2-bromoindene (21) under standard Suzuki reaction conditions. However, the yield of this reaction was low at low palladium catalyst loadings, due to a competitive hydrolysis reaction of 2,2-biphenyldiboronic acid (31). HTE techniques were used to find an economically viable protocol. Thus, use of the commercially available 1.0 molar solution of (n-Bu)4NOH in methanol with cosolvent toluene led to precipitation of the pure product in a fast and clean reaction, using only 0.7 mol % (0.35 mol % per C-C) of the expensive palladium catalyst.
