cze	O- a N-alkylované diketopyrrolopyrrolové deriváty	Byla provedena alkylace 3-phenyl-6-(2-thienyl)pyrrolo[3,4-c]pyrrole-1,4-dione s 1brom-2-ethylhexanu. Kromě očekávaného N,N´-dialkylovaného produktu byly poprvé izolovány oba možné N, O-dialkyl deriváty. Poloha alkyl substituentů ve všech třech dialkylovaných izomerech byla určena 2D 1H a 13C NMR spektroskopií.	NMR;alkylace;1,4-Diketo-pyrrolo[3,4-c]pyrrol
eng	O- and N-alkylated diketopyrrolopyrrole derivatives	The alkylation of 3-phenyl-6-(2-thienyl)pyrrolo[3,4-c]pyrrole-1,4-dione with 1-bromo-2-ethylhexane was performed. Besides the expected N,N´-dialkylated product, both possible N,O-dialkyl derivatives were isolated and identified for the first time. The position of the alkyl substituents in all three dialkylated isomers was determined by 2D 1H and 13C NMR spectroscopy.	1,4-Diketo-pyrrolo[3,4-c]pyrroles;Alkylation;O-Alkyl;NMR
