Cyclodimerization of 3,2-Stevens rearrangement products of 1,9-bisammonium salts containing a 5-oxanonane-2,7-diyne-1,9-diyl group
摘要:
1,9-Bisdimethylanimonium salts containing a 5-oxanonane-2,7-diyne-1,9-diyl along with alkoxycarbonylalkyl group, undergo double 3,2-Stevens rearrangement under the action of corresponding sodium alcoholates to form allene diamino esters whose prototropic isomerization under the action of dilute HCl gives rise to diketo diesters. The latter undergo 1,4-alcohol elimination under the reaction conditions and yield diene keto esters that cyclodimerize into cyclohexene derivatives. The bisammonium salt with a cyanomethyl group rearranges to form an allene dinitrile, which isomerizes into a diene compound.

1,9-Bisammonium salts with a common 5-oxanona-2,7-diyn-1,9-ylene group and two allyl groups undergo Stevens 3,2-rearrangement under the action of a suspension of KOH in benzene to form branched acetylenic diamines.

A series of quaternary bisammonium salts containing the common 5-oxanonane-2,7-diyne-1,9-diyl fragment and different alkoxycarbonylmethyl groups was synthesized. The surfactant properties and antimicrobial activity of these compounds were studied.
