A number of bicyclic macrolides with two stereogenic centres formally derived from ω-cycloalkyl fatty acids were synthesised by ring enlargement of cycloalkanones with novel chiral building blocks, easily available from yeast reduction products of β-keto esters. A comparison with structurally related monocyclic macrolides revealed surprising effects of structural variations on the olfactory properties
通过具有新的手性结构单元的环烷酮的环扩大,合成了许多具有两个正式衍生自ω-环烷基脂肪酸的立体异构中心的双环大环内酯类化合物,这些化合物很容易从β-酮酸酯的酵母还原产物中获得。与结构相关的单环大环内酯类化合物的比较揭示了结构变化对嗅觉特性的惊人影响。
