| Abstract: | 2,3-Dihyroxypyridine has been dialkylated with allyl bromide and methallyl chloride to give 1-allyl-3-allyloxy-2-pyridone ( 2 ) and 1-methallyl-3-methallyloxy-2-pyridone ( 3 ), respectively. These compounds readily undergo a Claisen rearrangement at 163° to give the bis-1,4-allyl-3-hydroxy-2-pyridone isomers, 4 and 5 , respectively. 2,3-Bisallyloxypyridine ( 8 ) and 2,3-bismethallyloxypyridine ( 9 ) were synthesized from 2-chloro-3-hydroxypyridine. |
