Abstract

N‐substituted (3‐aminopropyl)trifluorosilanes RRβ€²NCH~2~CH~2~CH~2~SiF~3~ I–V were synthesized in order to investigate the effect of the substituents at the nitrogen atom on the N β†’ Si intramolecular interaction. Compounds I–V were prepared by the reaction of KF with F~3~BN(CH~2~CH~2~CH~2~SiF~3~)RRβ€² or H(RRβ€²NCH~2~CH~2~CH~2~SiF~4~). The structures of compounds were confirmed by ^1^H, ^13^C, ^19^F, ^29^Si NMR and IR spectroscopy. The spectral data suggest a pentacoordination at silicon in compounds I (R = Rβ€² = H) and II (R = Rβ€² = Me) resulting from a relatively strong N β†’ Si intramolecular bonding.

The syntheses and a preliminary pharmacological evaluation of some aminopropylindolizines and aminopropyltetrahydroindolizines are reported. All compounds showed anti-5-hydroxytryptamine, anti-histamine, and antiacetylcholine activities. Some also exhibited weak CNS activity.

## Abstract Under electron impact, 3‐aryl‐4‐hydroxyisoquinolines form [M – H]^+^, [M – CO]^+^ and [M – H – CO]^+^ ions with a subsequent elimination of HCN or CH~3~CN. A cyclic structure for the [M – H]^+^ ion is suggested. The primary act of fragmentation of the corresponding methyle ether derivat
