Abstract

Dialkylation of cyclohexanone and spiro [5, 5] undecanones with 1, 5-dibromopentane or 1, 1-bis (2-bromo-ethyl) cyclohexane (IV) gave seven di-, tri-and tetraspiro ketones (V–XI), which embody four new polyspiro ring systems. Four polyspiro ketones could be reduced according to the Wolff-Kishner method giving three new polyspiro hydrocarbons (XXI— XXIII), while reduction with lithium aluminium hydride gave polyspiro alcohols (XXIV and ...
