Reactions de cycloaddition [4 + 2] sous micro - ondes des derives du glyoxal
摘要:
Hetero Diels-Alder reactions of methylglyoxylate and glyoxal monoacetal with 2-methyl-1,3-pentadiene have been studied under pressure in a microwave oven. Reaction times were dramatically reduced and degradation and polymerisation were avoided.
