A series of odoriferous cyclic ethers, including nerol oxide (1), Florol® (2), Florol methyl ether (3), and Pityol® methyl ether (4b), were prepared by a versatile synthetic protocol based on co-halogenation with 1,3-dibromo-5,5-dimethylhydantoin (= 1,3-dibromo-5,5-dimethylimidazolidine-2,4-dione; DDH) as the key step. The methodology provides a facile access to important perfumery molecules from abundantly
一系列有气味的环醚,包括橙花醇氧化物(的1),Florol ®(2),Florol甲基醚(3),和Pityol ®甲基醚(图4b)中,通过制备一种多用途的基于共卤化1合成的协议关键步骤是1,3-二溴-5,5-二甲基乙内酰脲(= 1,3-二溴-5,5-二甲基咪唑烷-2,4-二酮; DDH)。该方法提供了从丰富的单萜醇中轻松获取重要香料分子的途径。
