## Abstract The synthesis of spiroketals from nitro ketones is described. Racemic __trans__‐2‐Methyl‐1,7‐dioxaspiro[5.5]undecane (1a), and 2,8‐dimethyl‐1,7‐dioxaspiro[5.5]undecane (1b) are synthesized as a mixture of __trans__, __trans__ and __trans__, __cis__ isomers in a ratio of 6.5:3.5 (separab
