General description

Methyl 1-bromocyclohexanecarboxylate reacts with zinc and substituted chalcones to yield the corresponding spiro-3,4-dihydropyran-2-one derivatives, 3-aryl-5-aryl-2-oxaspiro[5.5]undec-3-en-1-ones.[1] Reformatsky reaction of methyl 1-bromocyclohexanecarboxylate with 2-aryl-2-oxoacetaldehyde is reported.[2] Methyl 1-bromocyclohexanecarboxylate reacts with zinc and amides or methylamides of 3-aryl-2-cyanopropenoic acids to yield 5-aryl-1,3-dioxo-2-azaspiro[5.5]undecane-4-carbonitriles or 5-aryl-2-methyl-1,3-dioxo-2-azaspiro[5.5]undecane-4-carbonitriles.[3]

Application

Methyl 1-bromocyclohexanecarboxylate may be used in the improved method of preparation of methyl 3-oxo-1-cyclohexene-1-carboxylate.[4] It may be used in the Reformatsky synthesis of 16-aryl-15-oxadispiro[5.1.5.3]hexadecane-7,14-diones.[5]
