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.
