The title compound (1) has been prepared form indan-1-one by Birch reduction and methylation followed by the introduction of a further double bond, enolisation of the ketone, and O-methylation. The tetraenol ether (1) is the first 3aH-indene derivative to be isolated. It is shown to be oxidised by air to the Z-cinnamic ester (5), and to undergo ready rearrangement to the 1H-indene (7).

3-Methoxy-3a-methyl-3aH-indene (4) has been synthesised and is isolated as an unstable, readily oxidised oil, which undergoes [8 + 2]cycloaddition with 4-phenyltriazoline-3,5-dione and with dimethyl acetylene-dicarboxylate.
