Reaction of 2-nitro and 3-nitro-2-cyclohexenone acetals: Preparation of useful intermediates

Preparation of 2-nitro-2-cyclohexenone acetal 31 starting from 2-nitrocyclohexanone acetal 29 has been reported for the first time. This compound as well as 3-nitro-2-cyclohexenone acetal 1, whose synthesis has been reported by us earlier, react with a variety of nucleophiles to form highly functionalised intermediates. One of them viz. 21 is converted into a bicyclic α-methylene-γ-lactone 24 using radical chemistry.

Photochemical Reactivity of α-Sulfonyloxy Enones: An Easy Method for Arylation of 1,2-Diketones

3-Aryl-1,2-cyclohexanediones 4 are prepared conveniently by photolysis of the corresponding 2-((arylsulfonyl)oxy)cyclohex-2-enones 1.The reaction was shown to occur from a triplet excited state.A biphotonic process involving the normal photo-Fries product 14 as an intermediate was ruled out by preparing and irradiating this compound.The difference of reactivity between 1 and 2-((arylsulfonyl)amido)cyclohexenones is discussed.
