Total Synthesis of Lissodendoric Acid A (Garg, 2023)

An organic chemistry minilecture on the 'Total Synthesis of Lissodendoric Acid A Via Stereospecific Trapping of a Strained Cyclic Allene' by Francesca M. Ippoliti, Nathan J. Adamson, Laura G. Wonilowicz, Daniel J. Nasrallah, Evan R. Darzi, Joyann S. Donaldson, Neil K. Garg*. It features a remarkably selective allene cycloaddition to build the azadecalin core, allowing for a ring closing metathesis reaction to form the macrocycle and selective reduction to complete the synthesis. ERRATUM: Pd shown for the first step of the Suzuki Coupling should be a Pd(0) complex. SUPPORT THE CHANNEL ON PATREON:   / simplifyingsynthesis   NMR Spectroscopy in music: J.
