We synthesized and investigated the NMDA and σ1 receptor affinity of enantiomericallypure 2-(2-phenyl-1,3-dioxan-4-yl)ethanamines 17–26. The primary amines (R,R)-18–20 with an axially oriented phenyl moiety in position 2 interacted with high enantioselectivity (eudismic ratios 70–130) and high affinity (Ki((R,R)-19) = 13 nM) with the PCP binding site of the NMDA receptor.

LiAlH4 reduction. The highest NMDA receptor affinity was found for 1,3-dioxanes with a phenyl and an ethyl residue at the acetalic position (23) followed by diphenyl (22) and monophenyl derivatives (13). Generally the NMDA affinity of primary amines is higher than the NMDA affinity of secondary and tertiary amines. Altogether the primary amine 23a (Ki = 24 nM) represents the most promising NMDA receptor
