Chemoenzymatic synthesis and binding affinity of novel (R)- and (S)-3-aminomethyl-1-tetralones, potential atypical antipsychotics
摘要:
A series of (R)- and (S)-3-aminomethyl-1-tetralones, conformationally constrained analogues of haloperidol, have been obtained by enzymatic resolution of the corresponding racemic 3-hydroxymethyl-1-tetralones using Pseudomonasfluorescens lipase. Their binding affinities at dopamine D-2 and serotonin 5-HT2A and 5-HT2C receptors were determined showing in some cases an atypical antipsychotic profile with Meltzer's ratio higher than 1.30.

Kinetic resolution of 3-hydroxymethylbenzocycloalkanols by selective asymmetric hydrogen-transfer oxidation
摘要:
Kinetic resolution of 3-hydroxymethylbenzocycloalkanols was performed by selective asymmetric hydrogen-transfer oxidation using the Ru(II)-(S,S)-TsDPEN catalyst. Thus, several 3-hydroxymethyl-1-tetralols 7a-d afforded (1R,3R)-3-hydroxymethyl-1-tetralols (1R,3R)-7a-d and (S)-3-hydroxymethyl-1-tetralones (S)-9a-d, and 3-hydroxymethyl-1-indanol 7e gave (1R,3S)3-hydroxymethyl-1-indanol (1R,3S)-7e and (R)-3-hydroxymethyl-1-indanone (R)-9e, with high enantioselectivities.
