Methyl 3-alkylazulene-1-carboxylates were synthesized in high yields by the reaction of 3-methoxycarbonyl-2H-cycloheptafuran-2-one with in situ generated morpholine enamines of aldehydes.Treatment of the esters with 100percent phosphoric acid gave 1-alkylazulenes in excellent yields.Azulene was also synthesized in a good yield via methyl azulene-1-carboxylate with a modification of this method.
