The 4‐ulose and the 3‐ulose, both derived in two steps from the α‐methyl glycoside of N‐acetyl‐D‐glucosamine (GlcNAc), act as organocatalysts in the asymmetricepoxidation of alkenes, with unprecedented complementary enantioselectivity. The best results are found with α,β‐unsaturated esters as substrates, with enantiomeric ratios up to 90:10 and 11:89, respectively.
An object of the present invention is to provide an auxin biosynthesis inhibitor superior to L-AOPP. The object can be attained by a compound represented by general formula (I): wherein, R1 to R5 and X are the same as defined in the specification or a salt or solvate thereof.
