Convenient syntheses of (E)-2-(arylmethylene)-1,4-butanediols 2a-c, 2-(aryl)-3-methylenetetrahydrofurans 4a,c, 3-(arylmethylene) -2-methyl-2,5-pentanediols 7a-c, 4-(arylmethylene)-3-ethyl- 3,6-hexanediols 7d-f, 2,2-dialky1-3-(arylmethylene)tetrahydrofurans 9a-f and 2,2-dialkyl-3-(arylmethyl)tetrahydrofurans 10a-b,10d-e are described. The synthetic utility of the title compounds is obvious from the ease of preparation of these new type of tetrahydrofuran derivatives.
