Cycloalkenobezofurans 5a-d were prepared in one-pot reaction from methoxyhydroquinone, 2,6- and 2,3-dialkoxyhydroquinone (1) with cycloalkenediol (2). Reaction between the isomeric 2,5-dialkoxyhydroquinones (9) with diol 2 led to the formation of monoalkoxybenzofurans 5d-g with the loss of an alkoxy group.
