We report a new general synthesis of damascones. In the presence of acids, 7, 8-dehydro-β-ionole (10) or the related diols 11 are converted into a mixture of β-damascone (2) and the 7, 8-dehydrotheaspiranes (19). In the same way the 6-hydroxy-7, 8-dehydro-α-ionoles 12 are transformed into a mixture of β-damascenone (3) and the 8-oxatheaspiranes (20). The reaction Provides access to damascone derivatives
我们报告了一个新的一般合成的大马士革。在酸的存在下,将7,8-脱氢-β-紫罗兰(10)或相关的二醇11转化为β-金刚烷烯(2)和7,8-脱氢theaspiranes(19)的混合物。以相同的方式,将6-羟基-7、8-脱氢-α-离子基团12转化为β-大马烯酮(3)和8-氧杂螺环烷(20)的混合物。该反应提供了访问大马酮衍生物4 - 7已在自然界中发现。
