  Concise and Stereoselective Syntheses of the Eight Natural Ant Defense Alkaloids (+)-Tetraponerine-1 to (+)-Tetraponerine-8 According to the CN(R,S) Strategy

  摘要：

  The asymmetric syntheses of all the known defense alkaloids of the ant Tetraponera sp. tetraponerines T-1 to T-8 have been accomplished in five or six steps with 20-45% overall yields. The synthesis involved in the cross-condensation of (R)-piperidin-2-ylacetaldehyde with 4-aminobutyraldehyde which upon quenching by cyanide ion gave a stable tricyclic amino nitrile 3 with both a high yield and complete diastereoselectivity. This amino nitrile is the common precursor of four tetraponerines. A similar synthesis using (R)-pyrrolidine-2-ylacetaldehyde provided the tricyclic amino nitrile 2 precursor of the four other tetraponerines.

  The asymmetric syntheses of all eight tetraponerine alkaloids (T1–T8) were achieved using the diastereoselective conjugate additions of lithium amide reagents in the key stereodefining steps. Conjugate addition of either lithium (R)-N-allyl-N-(α-methylbenzyl)amide or lithium (R)-N-(but-3-en-1-yl)-N-(α-methylbenzyl)amide to tert-butyl sorbate was followed by ring-closing metathesis of the resultant

• Natural Tetraponerines: A General Synthesis and Antiproliferative Activity

  DOI：10.1021/jo500446f

  日期：2014.5.2

  A stereocontrolled general methodology to access all natural tetraponerines from (+)-T1 to (+)-T8 is detailed. Two consecutive indium-mediated aminoallylations with the appropriate enantiomer of chiral N-tert-butylsulfinamide and a thermodynamic control at the aminal stereocenter allow the formation of each natural tetraponerine with excellent stereoselectivity. The use of 4-bromobutanal in the first aminoallylation leads to the formation of 5-6-5 tetraponerines, while 5-bromopentanal is required to build the scaffold of 6-6-5 tetraponerines. A cross-metathesis reaction of the second aminoallylation product with cis-3-hexene is used to elongate the side chain up to 5 carbons so as to prepare the tetraponerines T5 to T8. The anticancer activity of these heavier tetraponerines against four different carcinoma human cell lines is examined, observing a promising cytotcodc activity of (+)-T7 against breast carcinoma cell line MCF-7.

  Evidence is presented showing that tetraponerine-6 2a from Tetraponera sp. ants is biosynthesized from two molecules of putrescine and a seven-carbon moiety coming from an eight-carbon polyacetate chain through decarboxylation, in contrast with tetraponerine-8 1a, which derives from one putrescine unit and a twelve-carbon polyacetate precursor.
