Abstract

aza-spiro-(4,5)-decane-7,9-dione a pharmaceutical intermediate, of glu formula (1) is prepd from 3,3-tetra: methylene-glutane-acid (11) and acetic acetic-anhydride. 8-oxa-spiro-(4,5) decane-7,9-dione is not isolated from the reaction mix, while acetic-acid forming during reaction is removed, the reaction mix is treated with ammonium-acetate. High yield, high purity prods are obtd in this one-step reaction
