Abstract
Regio- and stereoselective hydrostannylation of alkyl ethynyl ethers generates alkenyl ethers, which are useful building blocks in organic synthesis. This efficient synthetic method, however, is limited. Here, we report not only an efficient method for a highly regio- and stereoselective Pd-catalyzed hydrostannylation of alkyl ethynyl ethers but also a scalable synthesis and construction of the core framework of luminamicin possessing all functional groups and stereocenters.

Abstract
The nargenicin family of antibiotic macrolides comprise a group of bacterial natural products with a rare ether bridged cis-decalin moiety and a narrow spectrum of activity. Most family members were identified almost four decades ago and were placed on the shelf due to the numbers of broad-spectrum compounds available at the time. However, in light of rising rates of antimicrobial resistance, there has been a renewed interest in the use of narrow-spectrum antimicrobials. Here, we review the history of this family of compounds, including synthetic approaches, and highlight the recently uncovered genetic basis for nargenicin production. Given the renewed pharmaceutical interest in these compounds, we also investigate structure-activity relationships among these molecules, with a view to the future development of members of this unusual antibiotic family.
