Simple synthesis of eudesmin through oxidative coupling of carbanions and reductive catalytic hydrogenation of diketo diester

A simple synthesis of eudesmin (1) is described. The key fragments were diol 13, dicarbethoxyethane 4, and diketo diester 5, which were prepared via reductive catalytic hydrogenation and oxidative intermolecular coupling of carbanions. This method is useful to generate the core skeleton of an endo-endo furofuran ring. Copyright Taylor & Francis Group, LLC.

Efficient selective formation of C-C single bonds and C=C double bonds by NBS-promoted oxidative coupling of β-keto esters

A new application of NBS, which results in the oxidative coupling of β-keto esters to selectively form C-C single and C=C double bonds, can be controlled by the amount of NBS and t-BuOK employed. This methodology adds a new entry to C-C single and C=C double-bond formation between active methylene groups under mild conditions with high selectivity. Copyright Taylor & Francis Group, LLC.
