title: Multistep solution-phase parallel synthesis of spiperone analogues.
abstract: A flexible, multistep parallel synthesis of spiperone analogues is described. A library of 4-substituted piperidines, assembled utilizing reductive amination and acylation protocols, was alkylated either homogeneously or heterogeneously, exploiting a product release only concept, to afford an oxa-series of spiperone analogues. Screening of the products at 5-HT2 and D2 receptors revealed 5-HT2A antagonists with improved selectivity compared to spiperone and AMI-193.
