Eu(OTf)<sub>3</sub>-Catalyzed Highly Regioselective Nucleophilic Ring Opening of 2,3-Epoxy Alcohols: An Efficient Entry to 3-Substituted 1,2-Diol Derivatives
In our study of the totalsynthesis of (+)-irciniastatin A, we found a need to develop a method that enables a C3-selective nucleophilicringopening of 2,3-epoxyalcohol by MeOH, by which we found that the use of combined catalytic amounts of Eu(OTf)3 and 2,6-di-tert-butyl-4-methylpyridine (DTBMP) enables the intended transformation to obtain 3-methoxy-1,2-diol efficiently. Promising features of a

A study of the high pressure hydrogenation of pyrogallol over nickel, copper – chromium oxide, and palladium catalysts showed that yields of 35% to about 60% of cis-cis-cis-cyclohexane-l,2,3-triol ...
