WebAug 10, 2007 · The amidation reactions are sensitive to steric hindrance at the α positions of either the alcohol or the amine. Thus, when 2-methyl-1-butanol reacted with benzylamine, the corresponding amide was obtained in 70% yield, with the rest of the alcohol being converted to the ester 2-methylbutyl 2-methylbutanoate (Table 1, entry 4).A similar pattern was also … WebThe reaction conditions were successfully applied to allylic boronic esters 8q and 8r to form allylic amines in good yield. The reaction of 2-methylallylboronic ester 8r with p -anisidine did give a mixture of mono- and dialkylated products, but this is the only boronic ester for which we have observed dialkylation. how many gasoline refineries in canada
