Spiro undecane derivatives

High yields of cyclobutane derivatives are obtained from the bis-p-toluene-sulfonates of 1,3-diols, as is shown by the synthesis of diethyl dispiro[3.1.4.1 ]-undecane-2,2-dicarboxylate from 2,2-spiro [3,4]octanebis(methyl /7-toluene-sulfonate) and ethyl malonate (warming with sodium in xylene) 386...
