It has been shown by different methods that of the two 1,1-dimethyl-cyclohexan-3-ol-2-carboxylic acids described in two previous papers the acid m.p. 161° represents the trans and the other one, m.p. 118°, the cis form. The approximate proportions of these compounds obtained by catalytic reduction of the corresponding ketoester either in acid or in neutral solution are also mentioned. The hydroxy acids
通过不同的方法已经表明,在前两篇论文中描述的两种1,1,1-二甲基-环己-3-醇-2-羧酸中,酸mp 161°代表反式,另一酸mp 118°,顺式。还提到了通过在酸或中性溶液中催化还原相应的酮酯而获得的这些化合物的大约比例。以这种方式制备的羟基酸伴随有少量的它们的脱水产物,β-环戊二酸。
