title: Synthesis of spiro[isobenzofuran-1(3H),4'-piperidines] as potential central nervous system agents. 2. Compounds containing a heteroatom attached to nitrogen.
abstract: The synthesis and antitetrabenazine activity of a series of N-heteroatom derivatives of 3-phenylspiro[isobenzofuran-1,4'-piperidines] are reported. Optimal antitetrabenazine activity is associated with compounds containing a sterically unhindered, basic nitrogen. Hydroxylamines 6, 11, 12, and 13 possess the most significant activity with ED50's of 1.4, 3.5, 4.7, and 4.0, respectively.
