Abstract
Abstract The separation of 29 isomer pairs, namely three pairs of 5- and/or 8-substituted 1,2,3,4-tetrahydronaphthols, one pair of naphthalene derivatives (naphthalene-1,7-diol and naphthalene-1,6-diol) and 25 pairs of N-substituted 3-amino-1,2,3,4-tetrahydro-2-naphthols including their lactone derivatives, tetrahydro-4 H -naphth[2,3- b ][1,4]oxazin-2-ones in TLC system on silica or alumina was studied. The possibility of two-point contact with the adsorbent in the case of more strongly retained isomers and their edgewise orientation against its surface is discussed. Attention is also paid to the influence of substituents in position 3 of the 1,2,3,4-tetrahydro-2-naphthol ring system on the retention sequence of the respective isomers.
