New preparative routes to the isomeric damascones (2, 4 and 9) and β-damascenone (1) starting from the readily accessible ionone isoxazoles [11] are described. γ-Damascone (9) was prepared from 10 following the Büchi-Vederas transformation [11], while α- and β-damascone (4 and 2) were obtained as the end products of the reaction sequence: β-aminodamascones [11]β-ketodihydrodamascones (20 and 21) β
描述了从易得的紫罗兰酮异恶唑[11]开始的新的制备途径,可通往异构异构的大马士康糖(2、4和9)和β-大马烯酮(1)。在Büchi-Vederas转化后[10]由10制备γ-大马酮(9),而反应序列的最终产物为α-和β-大马康尼(4和2):β-氨基大马康尼[11]β -酮基二氢金刚烷酮(20和21)β-羟基二氢金刚烷酮(24和25)。β-大马士革酮(1然而,β-紫罗兰酮异恶唑(14)的环氧化物是通过桦木还原,然后用酸处理而形成的。
