In the course of an extended study of spiro compounds (2), a series of bis (hydroxyalky1) and bis-(haloalkyl) derivatives of alicyclic and heterocyclic materials. was prepared by essentially standard methods. These derivatives have been demonstrated (2d) to be useful in the synthesis of spiro and polyspiro compounds. The diols (Table I) obtained by lithium aluminum hydride reduction of the precursor diesters (3) were converted in high yield to ...
