In this report, we present a highly efficient approach for the synthesis of β,γ-disubstituted γ-butyrolactone motifs. This newly developed strategy is based on the combination of a diastereoselective aldol and a nickel carbene-mediated γ-butyrola

A seven-step asymmetric total synthesis of gymnothelignan N is detailed in the current report. The approach is based on an early-stage one-carbon homologative lactonization reaction, which we recently revisited and modified to construct the core γ-b

The first total synthesis of tetrahydrofuran dilignan gymnothelignan K is disclosed. The approach is based on implementing an early stage one-carbon homologative lactonization, which we recently disclosed, for constructing the γ-butyrolactone scaffo
