Production

Laboratory methods

• O-alkylation of salicylaldehyde with chloroacetic acid followed by dehydration of the resulting ether and decarboxylation.
• Perkin rearrangement, where a coumarin is reacted with a hydroxide:
• Diels–Alder reaction of nitro vinyl furans with various dienophiles:
• Cycloisomerization of alkyne ortho-substituted phenols:
