Prosopis

In addition to lupines, poison-hemlock and Nicotiana spp., other plant species of the genera Genista, Prosopis, Lobelia, Cytisus, Sophora, Pinus, Punica, Duboisia, Sedum, Withania, Carica, Hydrangea, Dichroa, Cassia, Ammondendron, Liparia, and Colidium contain potentially toxic and teratogenic piperidine alkaloids. Many plant species or varieties from these genera may be included in animal and human diets (Keeler and Crowe, 1984).

The natural occurrence of promelacacinidins was until recently restricted to the heartwoods of Prosopis glandulosa and Acacia melanoxylon. The investigations of the heartwood constituents of A. caffra and A. galpinii also revealed the presence of a limited number of promelacacinidins (Table 11.11) as well as mixed di- and trimeric proteracacinidin or promelacacinidins (see Table 11.10).

Stereoselective total syntheses of (-)-deoxoprosopinine (20) and (-)-deoxoprosophylline (21), derived respectively from the natural bases prosopinine and prosophylline, have been described the route adopted should be applicable to other related piperidine bases.20 Prosafrinine (22), a piperidine alkaloid of Prosopis africana, has been synthesized stereoselectively, along with pseudocar-pamic acid (23), as racemic varieties.21 Additional stereoselective syntheses of ( )-carpamic and ( )-azimic acids have been described.22... 

A number of a, a -disubstituted 3-piperidinol alkaloids have been found in Cassia or Prosopis species,[1] and, quite recently, alkaloids including this structural unit have also been isolated from ascidian.[2] Many of these alkaloids showed interesting pharmacological activities such as anesthetic, analgestic, and antibiotic activities. Clavepictines A and B, and pictamine, isolated from tunicate, by Cardellina, II[3] or Faulkner[4] and co-workers, possess 3-piperidinol structure. Lepadins A, B, and C, isolated from tunicate, by Steffan[5] and Andersen[6] and coworkers, also have this structural unit. We designed lactam 1 as a useful...
