A simple synthesis of acetyl and propionyl cyclododecanes
摘要:
1-Formyl-4,8-cyclododecadiene, obtained by hydroformylation of 1,5,9-cyclododecatriene, reacts with MeMgHal or EtMgHal to give 1-(1'hydroxyethyl)- or 1-(1'-hydroxypropyl)-4,8-cyclododecadiene, respectively. The hydrogenation of their double bonds and subsequent oxidation of the resulting alcohols afford, in high yields, acetyl- or propionylcyclododecane, respectively.
New 1-acyl- and 1-hydroxymethyl-cyclododecanes and -cyclododecenes. The new 1-acyl-cyclododecenes and -cyclododecanes are obtained by a Rupe or Meyer-Schuster rearrangement, with or without subsequent hydrogenation in the presence of Ni, Pd and Pt catalysts. The 1-acyl-cyclododecenes and -cyclododecanes are valuable scents of the basic type of the sought-after macrocyclic musk scents. Furthermore, they are used for the manufacture of numerous other new 1-substituted or 1-and 2-substituted cyclododecenes and cyclododecanes having good scent characteristics.
