Reactions of 2-bromobenzyl bromide and its analogues XVII and XXV with 2-hydroxythiophenol resulted in 11H-dibenz[b,f]-1,4-oxathiepin (Ia) and its 2-chloro (Ib) and 2-trifluoromethyl derivative (IC). Treatment of the lithium compounds derived from Ia and Ib with carbon dioxide and dimethylaminoalkyl chlorides gave compounds IIa, Va and VIab; modification of side chains led to amines IVa, VIIa and VIIIa. 11-(1-Methyl-4-piperidyl) derivatives Xbc were obtained by chlorination of compounds Ibc with sulfuryl chloride or N-chlorosuccinimide and the following treatment with 1-methyl-4-piperidylmagnesium chloride. Compound Ib was transformed by oxidation to the sulfone XX affording by treatment with sodium hydride and tert-aminoalkylchlorides the basic sulfones XXI and XXII. While the nuclearly unsubstituted amines with the aliphatic side chains (IVa and VIIa) have intensive antireserpine activity and are potential antidepressants, the 11-(1-methyl-4-piperidyl) derivatives with a substituent in position 2 of the skeleton (Xbc) are potential neuroleptics; the trifluoromethyl derivative Xc especially has outstanding cataleptic and antiapomorphine efficacy.
