Two efficient synthetic methods for preparation of 3-(trifluoromethyl)cyclobutane-1-carboxylic acid are reported starting from readily available 4-oxocyclobutane precursors. These cyclobutanones can be converted to their CF3 carbinols upon treatment with TMSCF3 and a fluoride source. The bis-carboxylate system 9 was deoxygenated by treatment of Bu3SnH and provided desired compound 1 upon decarboxylation

A new protocol for alcoholdeoxygenation that functions across a wide range of alcohol structures is reported. This approach combines the reductive potency of carbon dioxide radical anion with acidic additives to promote the kinetically slow C(sp3)−O bond cleavage.
