Synthesis of β‐Aryl‐α,β‐Dehydroaminophosphonates by Pd‐Catalyzed Fujiwara–Moritani C−C Coupling
European Journal of Organic Chemistry, Volume 27, Issue 18, May 13, 2024.β‐aryl‐N‐acetyl‐α,β‐dehydroaminophosphonic esters can be synthesized through oxidative Fujiwara–Moritani C−C coupling of different arenes with diethyl α,β‐dehydroaminophosphonate 1, process catalyzed by Pd2+ and assisted by Ag+. The reaction is regioselective to the E‐isomer and tolerates the presence of both electrodonating and electronwithdrawing ...

Asymmetric Organocatalyzed Synthesis of α‐Aminophosphinates via Thiourea Anion‐Binding Catalysis
European Journal of Organic Chemistry, Volume 27, Issue 11, March 18, 2024.P‐Stereogenic α‐aminophosphinates were obtained in high enantioselectivity via anion‐binding catalysis with thiourea catalysts, further expanding the range of nucleophiles that can be used in this type of catalysis. Abstract Thioureas catalyze the reaction of phosphonites with in situ‐generated isoquinolinium salts to give C and P‐stereogenic α ...
