Abstract

Starting with 5‐formyl‐6,7‐dimethyl‐5,6,7,8‐tetrahydropterine (II), a new synthesis of 5,6,7‐trimethyl‐5,6,7,8‐tetrahydropterine (III) is described. Thereby the chemical behaviour of the 5‐formyl group in II is investigated, in order to enable the unequivocal differentiation between formylation at position 5 and at position 10 in folic and tetrahydrofolic acid derivatives. ^13^C‐NMR. spectra of II and III are discussed.

## Abstract The ^13^C‐NMR.‐spectra of 7,8‐dihydropterines and 5,6,7,8‐tetrahydropterines show a large difference in the chemical shifts of the 4a‐ and 8a‐sp^2^‐carbon atoms. From the CNDO calculations it is apparent that there is a considerable difference in electron density at C(4a) and C(8a) atom
