Chai, Guo-Li published the artcileHydroxytetraphenylenes as Chiral Ligands: Application to Asymmetric Darzens Reaction of Diazoacetamide with Aldehydes, Name: ((1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonyl chloride, the publication is Synthesis (2017), 49(1), 181-187, database is CAplus.
Hydroxytetraphenylenes with rigid conformations are potential candidates for employment as chiral ligands in asym. synthesis. Highly diastereo- and enantioselective Darzens reactions between aldehydes and diazo-N,N-dimethylacetamide are catalyzed by a chiral titanium complex formed in situ from Ti(OiPr)4 and chiral 1,16-dihydroxytetraphenylene, giving cis-glycidic amides in moderate to high yields with excellent enantiomeric purities (40-99% yield, up to 99% ee).
