  Intramolecular [4 + 3]-cycloadditions of photochemically generated oxyallyl zwitterions: a route to functionalized cyclooctanoid skeletons

  摘要：

  [4 + 3]-Cycloaddition of photochemically generated, 4-pyrone derived oxyallyl zwitterions and furans was examined as a potential approach to keto-bridged cyclooctenes. In one case, intermolecular cycloaddition proceeded to give adduct 3 with complete diastereoselectivity and in moderate yield, but the reaction was not general. Substrates 5a-i were then prepared in one to three steps from either 3-methyl-4H-pyran-4-ones or 3-hydroxy-2-methyl-4H-pyran-4-one, and their viability in intramolecular [4 + 3]-cycloadditions was examined. Substrates 5a-e, in which the tether was attached to the incipient zwitterion via a carbon, underwent cycloaddition to give [4 + 3]-cycloadducts 7 and 8 in varying yields, along with small amounts of cage compound 9. In contrast, 5f-i, in which the tether was attached to the incipient zwitterion via an oxygen, gave only solvent-trapping products 10. In one case (5e), isomeric pyran-2-ones 11e/12e were produced in addition to [4+3]-cycloadduct 8e and cage compound 9e. Moreover, it was found that 11e and 12e both underwent subsequent photochemical crossed [4 + 4]-cycloadditions to give lactone-bridged cyclooctadienes 13e and 14e. The structures of 11e/12e and their [4 + 4]-cycloadducts were confirmed by synthesis of each of the 2-pyrones via alternative routes.

  Branching out! The catalytic asymmetric conjugate addition of glycinate Schiff bases to β‐substituted gem‐diactivated Michael acceptors under proton transfer conditions gives a variety of β‐branched α‐amino acids (see scheme; Dpm=diphenylmethylene, EWG=electron‐withdrawing group) with excellent levels of diastereo‐ (typically syn/anti >90:10) and enantiocontrol (90–99 % ee).

  Organocatalytic asymmetric Michael reaction of unmodified aldehydes to vinyl sulfones catalyzed by silylated biarylprolinol afforded the desired Michael products with exceptional enantioselectivity. The described enantioselective addition to vinyl sulfones, in combination with desulfonation, offers a unique, asymmetric entry to alpha-alkylated aldehydes and their derivatives.
