3-羰基-1-环己羧酸 | 3-oxo-cyclohexanecarboxylic acid | 16205-98-4 | C7H10O3 | 142.155 |
(1R,3S)-3-羟基环己烷-1-羧酸 | (+/-)-cis-3-Hydroxy-cyclohexancarbonsaeure | 21531-44-2 | C7H12O3 | 144.17 |
The syntheses are described of (1R,3S)- and (1S,3R)-3-aminocyclohexanecarboxylic acids via unsaturated intermediates suitable for tritium labelling. The absolute stereochemistry was determined by an alternative synthesis of the (1R,3S) isomer from (R)-3-oxocyclohexanecarboxylic acid. The (1S,3R) isomer showed a similar potency to GABA as an inhibitor of the uptake of radioactive GABA by rat brain slices whereas the (1R,3S) isomer was at least 20 times less potent.
