  Facile Entry to Substituted Decahydroquinoline Alkaloids. Total Synthesis of Lepadins A−E and H

  摘要：

  Condensation of a L-alanine derived delta-bromo-beta-silyloxy-propylamine with 1,3-cyclohexadione followed by alkylative cyclization produces a bicyclic enone. Diastereoselective Pt/C-catalyzed hydrogenation of this enone in HOAc provides a 5-oxo-cis-fused decahydroquinoline. Wittig olefination of this decahydroquinoline and subsequent epimerization of the resulting 5-formyl intermediate gives rise to a 5-beta-formyl decahydroquinoline exclusively. In a parallel procedure, Peterson reaction of this decahydroquinoline and subsequent hydrogenation of the generated 5-exo-olefin provides a decahydroquinoline with a 5-alpha-substituent predominantly. For these two diastereoselective processes, using the intermediates without N-protection as the substrates is essential because the corresponding N-Boc intermediates give poor diastereoselectivity. The intermediate with beta-form side chain is further converted into lepadins A-C via carbon chain elongation, while the intermediate with alpha-form side chain is transformed into lepadins D, E, and H and corresponding 5'-epimers via connection with two sulfones generated from two Sharpless epoxidation products. By comparison of the rotations and NMR data, the stereochemistry of lepadins D, E, and H is assigned as 2S, 3R, 4aS, 5S, 8aR, 5'R.

  Concise assignments of the C5' stereochemistry in (+)-lepadin F and (+)-lepadin G and the absolute configuration of (+)-lepadin G via the first total syntheses of (+)-5'-epi-lepadin F, (+)-lepadin G, and (+)-5'-epi-lepadin G are described. This work represents an Illustrative example in which a diastereomeric pair can possess sufficient spectroscopic difference for clear assignment despite differing only at a highly insulated acyclic stereocenter.
