Total synthesis of oxaphenalenone natural products
… lactone E through the use of crossed-Claisen condensation of an isochromanone substrate followed by an interesting Au(I)-mediated 6-endo-dig hydroarylation. Subsequent studies implemented closely-related synthetic operations to assemble a masked ortho-quinone methide (o-QM) bearing the …

Investigation of regulatory and functional diversity in an enzyme superfamily
… Analysis of one of the member subgroups, the Claisen condensation-like (CC-like) subgroup, identified the presence of an interesting pattern of functional and regulatory diversity. The CC-like subgroup has ~4300 sequences that catalyze the condensation of acetyl-CoA with six different -keto …

Anion Relay Cyclopropanation and Aryl Vinyl Cyclopropane Cope Rearrangements
… Presented herein is the development of a retro-Claisen condensation protocol to effect anion relay in the synthesis of vinyl cyclopropanes, and subsequent aromatic Cope rearrangement of those vinyl cyclopropanes. This protocol provides a supplementary method of anion relay utilizing readily …

Addressing the ongoing threat of antimicrobial resistance: synthetic investigations of novel amicetin and B-lactam antibiotics
… Novel AFAs are synthesized via a Ti-Claisen condensation between methyl formate, a methodology also previously developed within our research group. Unfortunately, due to difficulties encountered within the initial synthetic route and time constraints, we could not reach the …
