  • Convergent Synthesis of Polycyclic Ethers via the Intramolecular Allylation of α-Acetoxy Ethers and Subsequent Ring-Closing Metathesis

    with high stereoselectivities. Those cyclized products were subjected to ring-closing metathesis to afford the polycyclic ethers 38-42, 44, and 45 in good yields. The usefulness of the present methodology was demonstrated by the convergent synthesis of the CDEF ring system of brevetoxin B (1) and the CDEFG ring system of gambierol (2).

  • Solvent-Controlled Stereoselective Formation of a Cyclic Ether in the Lewis Acid-Mediated Allylation of an α-Chloroacetoxy Acyclic Ether. Very High Stereoselectivity in CH<sub>3</sub>CN vs Low Stereoselectivity in CH<sub>2</sub>Cl<sub>2</sub>

    The MgBr2-OEt2-mediated intramolecular allylation of a 4:1 diastereoisomeric mixture of the alpha-chloroacetoxyl ether la bearing the A-G/JK ring system of brevetoxin B in CH2Cl2 gave a 1: 1 diastereoisomeric mixture of the trans- and cis-cyclization products 4a and 5a having the A-G/I-K ring system, while that in CH3CN afforded the trans-isomer 4a nearly as the single product. To help clarify a reason for this marked solvent effect in the cyclization of the brevetoxin B precursor, DFT computations for the starting materials, intermediates, transition states, and products were carried out. The cyclization would proceed through a carbocation intermediate 3a having sp(2) flat structure (S(N)1 type mechanism) in CH2Cl2, in which the activation energies leading to both diastereoisomers are approximately identical, while in CH3CN alkylnitrilium salts 6a would be formed through the coordination of CH3CN to the carbocation leading to an sp(3)-type intermediate in which sever steric hindrance takes place in the transition state leading to the undesired diastereoisomer. The scope of this novel solvent-controlled stereo selectivity was tested for simple compounds. In small model compounds the marked solvent dependence was absent, but the model bearing two consecutive cyclic ether rings 1b exhibited a remarkable solvent effect similar to that observed in the brevetoxin B system.

  • Bridging of macrodithionolactones to bicyclic systems. Synthesis and modeling of oxapolycyclic frameworks

    A new reaction involving bridging of macrodithionolactones to bicyclic systems is described. A series of macrodiolides was prepared and converted to the requisite macrodithionolactones. The latter substrates were induced to undergo bridging across the macrocyclic ring by exposure to sodium naphthalenide, leading to stable bicyclic systems upon addition of methyl iodide. The mixed thioketals so obtained
