Selective Oxidation of Alcohols
635
was stirred for 4–5 h under reflux. After completion of the reaction, workup as
described previously followed by flash column chromatography on silica gel
(ethyl acetate/hexane, 1:1) gave the product (4) in 75% yield or the product
(6) in 67% yield, respectively. Spectral data of the products were identical
with those reported.
