The construction of a cycloalkyl ring at the alpha-position of aldehydes by cyclization of omega-haloaldimines is described. Alkylation of the corresponding aldimines with alpha,omega-dihaloalkanes followed by treatment with LDA results in a convenient access to alpha,alpha-cyclobisalkylated aldimines which are hydrolyzed to the alpha,alpha-cycloalkylaldehydes.
