摘要
Methyl 1-bromocyclopentane-, 1-bromocyclohexane-, and 1-bromocycloheptanecarboxylates react with zinc and 2,6-bis(arylmethylene)cyclohexanones to afford 4-aryl-8-(arylmethylene)-5,6,7,8-tetrahydrospiro[chromene-3,1′-cyclopentan]-2(4H)-ones, 4-aryl-8-(arylmethylene)-5,6,7,8-tetrahydrospiro[chromene-3,1′-cyclohexan]-2(4H)-ones, and 4-aryl-8-(arylmethylene)-5,6,7,8-tetrahydrospiro[chromene-3,1′-cycloheptan]-2(4H)-ones, respectively.
