An efficient preparation of 6-alkoxy-substituted benzocyclobutenones
Bungard,Morris
, p. 741 - 744 (2001)
A short, efficient route to 3-alkoxybenzynes has been developed, starting from readily available compounds. This has enabled rapid access to 6-alkoxybenzocyclobutenones, which are valuable synthetic intermediates.
