Abstract: Earlier described compounds 2b,c as semihydrates of 2,5-cyclohexadien-4-one-spiro-3’-(2’-ethoxycarbonylmethyl-5’,5’-dimethyl-l’pyrroline) (2c) and as 2,5-cyclohexadien-4-one-spiro-3’-(2’-phenyl-5’,5’-dimethyl-l’-pyrroline) (2b), after recording ¹³C NMR and mass spectra, were found to be ethyl N-[l-(p-hydroxyphenyl)-2-methylpropan-2-yl]malonamate (here 1a) and N-[l-(p-hydroxyphenyl)-2-methylpropan-2-yl]benzamide (here 1b). Named above spiro-compounds 2b,c are formed in the described conditions and can be detected by TLC; however, they are easily converted to amides (here 1a,b) during isolation as a result of hydrolysis in acidic media.
