- Abstract
- Cyclocondensation of industrially available [1,1′-bi(cyclohexane)]-1′-en-2-one (Wallach ketone) with aminoethanols under acid catalysis conditions leads to 6-(cyclohex-1-en-1-yl)-1-oxa-4-azaspiro[4.5]decanes in 56–88% yields. A series of ethanolamines (yields 73–96%) containing a hydrophobic [1,1′-bi(cyclohexane)]-1-ene fragment were obtained by reductive cleavage of these 1,3-oxazolidine derivatives under the action of NaBH. The synthesized amino alcohols have surface activity and are highly effective inhibitors of hydrochloric acid corrosion of carbon steel with a protective effect of up to 98.1%.
