Synthesis of Novel 4(5)-(5-Aminotetrahydropyran-2-yl)imidazole Derivatives and Their in Vivo Release of Neuronal Histamine Measured by Brain Microdialysis
and (2S,5S)-cis-stereoisomers 1a and 1b of 4(5)-(5-aminotetrahydropyran-2-yl)imidazole, which have two chiral centers and adopt a stable chair conformation, were synthesized via cyclization of diol intermediates 7 using L-glutamine as the starting material. Their enantiomers, (2S,5R)-trans-1c and (2R,5R)-cis-1d, were synthesized by the same methodology from D-glutamine. Stereo isomers 1a-d were converted
