  Rhodium-catalyzed reductive cyclization of 1,6-enynes and stereoselective synthesis of the putative structure of lucentamycin A and its stereoisomers

  摘要：

  A Rh-catalyzed diastereoselective reductive cyclization, mediated by hydrogen, of optically active 1,6-enynes using chiral BINAP was successfully applied to the total synthesis of four stereoisomers of the proposed structure of lucentamycin A. In order to synthesize two of these four stereoisomers, we successfully constructed chiral proline derivatives bearing cis-carbon substituents at C2 and C3 positions based on Krische's methodology, which has very rarely been reported. Anti-proliferative activities on HCT-116 cell line and NMR data of these four stereoisomers were compared with those of naturally occurring lucentamycine A. The results show that the proposed structure of lucentamycin A needs revision. (C) 2012 Elsevier Ltd. All rights reserved.

  Synthetic efforts toward the cytotoxic peptides lucentamycins A−D are described that resulted in the total synthesis and biological evaluation of 8-epi-lucentamycin A in 15 steps with 2.2% overall yield. The key epi-nonproteogenic 3-methyl-4-ethylideneproline was synthesized via a titanium-mediated cycloisomerization reaction.

  Bioinspired palladium(II)-catalyzed intramolecular cyclization of amino acid derivatives containing a vinyl iodide moiety by C−H activation enabled rapid access to a wide range of functionalized proline derivatives with an exocyclic double bond. Such functionalized prolines were used as intermediates for the total synthesis of several natural products: lucentamycin A, barmumycin, oxotomaymycin, and
