Abstract

3-Hydroxy-4-(trifluoromethyl)azetidin-2-ones were synthesized from the corresponding 3-benzyloxy-β-lactams and successfully transformed into new 3-chloro-4-(trifluoromethyl)azetidin-2-one building blocks. The latter chlorides were shown to be eligible precursors for the construction of CF3-containing aminopropanes, 1,3-oxazinanes, 1,3-oxazinan-2-ones, and aziridines. In addition, 3-hydroxy-4-(trifluoromethyl)azetidin-2-ones proved to be interesting substrates for the synthesis of novel 3-[2,2,2-trifluoro-1-(arylamino)ethyl]-1,4-dioxan-2-ones via intramolecular cyclization of 3-(2-hydroxyethoxy)-β-lactam intermediates.
