  Toxic piperidine alkaloids from pine (Pinus) and spruce (Picea) trees. New structures and a biosynthetic hypothesis

  摘要：

  A series of 2,6-disubstituted piperidine alkaloids have been isolated from several Pinus (pine) and Picea (spruce) species and characterized structurally. The pines appear to contain only cis-disubstituted piperidines, while the spruces contain both cis- and trans-disubstituted piperidines. The structural relationships among the alkaloids suggest a plausible biosynthetic scheme and a reason why previous attempts to elucidate the biosynthesis of pinidine failed beyond establishing its polyketide origin. A mixture of alkaloids from needles of Pinus ponderosa proved to be highly teratogenic. The alkaloids might therefore be involved in so-called pine needle abortion which occurs in pregnant range cows which feed on Ponderosa pine needles.

  A Diastereoselective Intramolecular Hydroamination Approach to the Syntheses of (+)-, (±)-, and (−)-Pinidinol

  摘要：

  A diastereoselective, lanthanocene-catalyzed, intramolecular hydroamination reaction was applied to the preparation of 2,6-disubstituted piperidines. Various metal/ligand arrays in the catalysts were examined using a model substrate to allow optimization of the diastereoselectivity. It was determined that the relationship between metal size and ligand bulk plays an integral role in the transformation. The complex Cp*2NdCH(TMS)(2) converted 2-substituted 8-nonen-4-amines to 2,6-disubsituted piperidines with greater than 100:1 selectivity for the formation of the cis isomer. A short synthesis of pinidinol, an alkaloid isolated from various pine and spruce species, was then carried out to exploit this stereoselective reaction.

  A new diastereoselective synthesis of 2,6-disubstituted piperidinic alkaloids is presented. Three natural compounds, the (−)-pinidinone 1a, the (+)-dihydropinidine 1b and the (−)-pinidinol 1c were prepared from optically pure (6R)-6-methylpiperidin-2-one 2. This method is based on the chemo- and diastereocontrolled reductions of an exocyclic β-enamino ketone.
