In one embodiment, the present application discloses methods to selectively synthesize higher alcohols and hydrocarbons useful as fuels and industrial chemicals from syngas and biomass. Ketene and ketonization chemistry along with hydrogenation reactions are used to synthesize fuels and chemicals. In another embodiment, ketene used to form fuels and chemicals may be manufactured from acetic acid which in turn can be synthesized from synthesis gas which is produced from coal, biomass, natural gas, etc.

stereoselectivity of the cyclizations depends on relative stability of the cyclization-generated radicals. Therefore, the oxidative free-radical cyclization of allyl alpha-methyl-beta-ketoester 5a with Mn(OAc)(3) gives a cis product as a major product, while the same oxidative free-radical cyclizations of substitutedallyl alpha-methyl-beta-ketoesters 5b and 5c with Mn(OAc)(3) produce trans products as major
