Gallium-Mediated Allyl Transfer from Bulky Homoallylic Alcohol to Aldehydes via Retro-allylation:  Stereoselective Synthesis of Both erythro- and threo-Homoallylic Alcohols¹

, 2016
Retro-allylation of bulky gallium homoallylic alkoxides occurs to generate (Z)- and (E)-crotylgallium reagents stereospecifically, starting from erythro- and threo-homoallylic alcohols, respectively.

Asymmetric Iron‐Catalyzed Vicinal C(sp3)─H Diamination of Carboxylic Acids

Angewandte Chemie, Volume 138, Issue 32, 3 August 2026.
An iron‐catalyzed vicinal α,β‐C(sp3)─H diamination of readily available carboxylic acids furnishes chiral α,β‐diamino acids in a single pot with high regio‐, diastereo‐, and enantioselectivity (up to >20:1 dr and >99% ee). ABSTRACT The direct construction of chiral 1,2‐diamines through the stereoselective functionalization of two vicinal C(sp3)─H bonds

Total Synthesis of Chaxalactin B, a Rare 22‐Membered Macrolactone

ChemistryEurope, Volume 4, Issue 10, October 2026.
The first total synthesis of the antibacterial 22‐membered macrolactone chaxalactin B has been accomplished in 23 steps (longest linear sequence). Key transformations feature a stereoselective Marshall propargylation, a Suzuki–Miyaura coupling for the assembly of the main C1–C9 and C10–C25 fragments, and a late‐stage Shiina macrolactonization ...
