P. Benitez et al., PREPARATION OF OMEGA-HYDROXY ACIDS BY REDUCTION OF ALPHA,OMEGA-METHYLENE DIESTERS WITH NABH4, Synthetic communications, 27(10), 1997, pp. 1697-1702
By reaction of the dicesium salts of long chain dicarboxylic acids (C
atoms > 9) with methylene iodide the corresponding methylene diesters
were prepared. These acylals, by reduction with NaBH4 in THF, give the
corresponding omega-hydroxy acids.
