Reformatsky reagents obtained from methyl 1-bromocyclohexane- and 1-bromocyclopentane-1-carboxylates reacted with aromatic aldehyde phenyl- and benzoylhydrazones to give 3-aryl-2-phenylamino-2azaspiro[3.5]nonan-, 3-aryl-2-phenylamino-2-azaspiro[3.4]octan-, 3-aryl-2-benzoylamino-2-azaspiro[3.5]nonan-, and 3-aryl-2-benzoylamino-2-azaspiro [3.4]octan-1-ones, respectively. The reaction of furan-2-carbaldehyde phenylhydrazone with methyl 1-bromocyclohexane-1-carboxylate and zinc led to the formation of 4-(2-furyl)-2-phenyl-2,3-diazaspiro[4.5]decan-1-one.
