A new one-pot strategy for the synthesis of a series of new N-substituted 3-trifluoroacetyl pyrroles is presented. These compounds were obtained by the reaction of 3-trifluoroacetyl-4,5-dihydrofuran with primary amines, which generated 1,1,1-trifluoro-3-(2-hydroxyethyl)-4-alkylaminobut-3-en-2-one intermediates. In most cases these intermediates were not stable enough to be isolated. Thus, in the same

Amino acetals of the general formula MeCH(OR)(OXNH2) (R = Et, Bu, X = CH2CH2, CH2CH2CH2, CH2CMe2) were synthesized in 53–91% yield by acid-catalyzed reaction of N-(2-hydroxyethyl)-, N-(3-hydroxypropyl)-, and N-(2-hydroxy-1,1-dimethylethyl)-2,2,2-trifluoroacetamides with vinyl ethers, followed by removal of the trifluoroacetyl protection by alkaline hydrolysis.

New low molecular mass enantiopure organogelators (1R,4R)-1, (S)-2, (R)-3 and (R)-4 were found; racemates (R,S)-3 and (R,S)-4 have only a moderate gelating power, whereas (R,S)-1 and (R,S)-2 do not show gelating properties at all.
