  Synthesis and Structure Revision of Calyxin Natural Products

  摘要：

  Tandem Prins cyclization and Friedel-Crafts reaction with an electron-rich aromatic ring were used to prepare the core structures of calyxin natural products. The proposed structure of epicalyxin F was prepared and shown to be incorrect. Several calyxin natural products, including calyxin F and L, were synthesized, and the structures were reassigned on the basis of NMR data and synthetic correlations.

• Catalytic asymmetric hetero-Diels–Alder route to a key intermediate for the synthesis of calyxin L

  A catalytic asymmetric formal synthesis of diarylheptanoid natural product calyxin L has been achieved by incorporating an enantio- and diastereoselective hetero-Diels-Alder (HDA) reaction, a Suzuki-Miyaura coupling, and a stereocontrolled catalytic hydrogenation of 2,4,6-trisubstituted dihydropyran as the key steps. The HDA reaction between 4-(4-benzyloxyphenyl)-2-triethylsilyloxy-1,3-butadiene and (4-benzenesulfonyloxyphenyl)propynal catalyzed by dirhodium(II) tetrakis[(R)-3-(benzene-fused-phthalimido)-2-piperidinonate], Rh-2(R-BPTPI)(4), provided cis-2,6-disubstituted tetrahydropyran-4-one in 91% yield with 91% ee.
