An efficient one-pot synthesis of optically active β-alkyl-substituted alcohols through a tandem copper-catalyzed asymmetric allylic alkylation (AAA) with organolithium reagents and reductive ozonolysis is presented. Furthermore, hydroboration-oxidation following the Cu-catalyzed AAA leads to the corresponding homochiral γ-alkyl-substituted alcohols.

Described herein is the first synthesis of the monobenz-annulated 5,5-spiroketals danshenspiroketallactone and epi-danshen-spiroketallactone, two components of the traditional Chinese medicine Danshen. Key features of the synthesis include a directed metallation-lactonisation sequence to install the isobenzofuranone moiety and an oxidative radical cyclisation to afford the monobenz-annulated 5,5-spiroketal.
