| Abstract: | The reaction of esters of 4-R-3-methyl-2,3,4,5-diepoxyvaleric acids with secondary amines leads to the formation of esters of 4-R-5-dialkylamino-4-hydroxy-3-methyl-2,3-epoxyvaleric acids. The reduction of the latter with lithium tetrahydroaluminate and the cyclization of the reduction products in the presence of p-toluenesulfonic acid has given 2-dialkylaminoethyltetrahydrofuran-3-ols, the methiodides of which possess ganglion-blocking activity.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 11, pp. 1443–1446, November, 1973. |
