The synthesis of porphyrin-linked indolizine has been achieved for the first time in a simple process from the reaction between a 5-formylindolizine (8) and dipyrrolomethane (10) giving the desired 1,7-bisindolidinoporphyrin (12). The electronic effect of the heterocyclic nuclei (12) is prominently observed in the Soret band of the UV - VIS spectrum. Temperature-dependence 1H NMR analysis of 12 suggests the existence of an association of 12 causing restricted rotation around the bond between indolizine and porphyrin.

The present invention relates to compositions comprising 4-Oxo-piperidine-carboxylates and derivatives thereof, for example derivatives substituted with phenyl, nitrophenyl or benzyl groups. It also teaches the medical use of these and related compounds for treatment of retroviral diseases, in particular, HIV and HTLV, proliferative diseases, in particular CML and Trypanosomiasis.

On the basis of structural and/or aroma analogies to known thrips (Thysanoptera: Thripidae) lures, 35 compounds (18 pyridine derivatives, 13 benzene derivatives, and 4 other compounds), consisting of both synthetic and naturally occurring compounds, were screened for their ability to bring about increased thrips capture in field experiments using water traps in Canterbury, New Zealand. Most of the thrips caught were New Zealand flower thrips (NZFT) (Thrips obscuratus) or onion thrips (OT) (Thrips tabaci). The greatest increase in capture for NZFT (158 times for ♀ cf. to water control) was for the known lure ethyl nicotinate, a 3-pyridyl ester. Ethyl isonicotinate, the 4-pyridyl regioisomer of ethyl nicotinate, not previously reported as a thrips lure, provided the greatest increases in capture for OT (31 times) of any of the compounds tested, significantly more than ethyl nicotinate. Other 4-pyridyl carbonyl compounds, including ethyl 4-pyridyl ketone, also increased OT capture significantly. The natural floral compound cis-jasmone, which increased trap capture of NZFT (♀ 42 times, ♂ 25 times) but not OT, is reported as a thrips lure for the first time.
