  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.

• Total synthesis of (+)-monocerin via tandem dihydroxylation-S_N2 cyclization and a copper mediated tandem cyanation–lactonization approach

  DOI：10.1039/c4ob00965g

  日期：——

  A simple and novel synthesis of (+)-monocerin was achieved from 3-buten-1-ol employing HKR, Julia olefination, intramolecular tandem Sharpless asymmetric dihydroxylation-S_N2 cyclization and a novel copper mediated tandem cyanation–cyclization as the key steps.

  使用HKR、Julia烯化、分子内串联Sharpless不对称双羟化-SN2环化和一种新型铜介导的串联氰化-环化作为关键步骤，从3-丁烯-1-醇成功合成了(+)-单萜素。
