Evidence is presented that contradicts an earlier finding that, in the absence of sterichindrance, the coupling reaction of alkylcarbonyloxymethyl (ACOM) halides with phenols favors acylated product. A one-step synthesis is used to generate sterically unhindered ACOM iodides, which are then reacted with several phenols to give mainly alkylated phenol.
Methods of using propionoyloxymethyl propionate (“POMP”) and butyroyloxymethyl butyrate (“BOMB”) are disclosed. Methods of treating an illness, including cancer, hemological disorders and inherited metabolic disorders, as well as other conditions, using these compounds are disclosed. The compounds are effective in the inhibition of histone deacetylase.
