Irradiation of 1-naphthol (1a) and its 2-alkyl and 6-methoxy derivatives 1b-d with 5 equiv of AlCl3 or AlBr3 in CH2Cl2 gave (chloromethyl)indanones 4a-d in 41-72% yields. Irradiation of 1a with AlBr3 in CH2Br2 afforded (bromomethyl)indanone 5a in 54%. 3-Methyl derivative 1e was unreactive and 4-methyl derivative 1f underwent isomerization to 1e.

A series of novel conformationally restricted butyrophenones (2-(aminoethyl)- and 3-(aminomethyl)thieno- or benzocycloalkanones bearing (6-fluorobenzisoxazolyl)piperidine, (p-fluorobenzoyl)piperidine, (o-methoxyphenyl)piperazine, or linear butyrophenone fragments) were prepared and evaluated as atypicalantipsychotic agents by in vitro assays of affinity for dopamine receptors (D(1), D(2)) and serotonin
