Phosphine-Triggered Selectivity Switch in Silver-Catalyzed o-Alkynylbenzohydroxamic Acid Cycloisomerizations

12-Sep-2016 | Xavier Bantreil; Aurélie Bourderioux; Pierre Mateo; Caroline E. Hagerman; Mohamed Selkti; Etienne Brachet; Philippe ..., Organic Letters, 2016

A silver-catalyzed cycloisomerization reaction of a series of o-alkynylbenzohydroxamic acids is reported. Several 5-exo-dig and 6-endo-dig modes of cyclization were observed with the nitrogen or oxygen atoms of the amide group acting as nucleophiles. The selectivity was strongly dependent on the ...

Structure Revision of an Acorane Sesquiterpene Cordycepol A

09-Sep-2016 | D. Sai Reddy; Andrei G. Kutateladze, Organic Letters, 2016

Structure revision of a recently reported spirodecane sesquiterpene, cordycepol A, from fungi Cordyceps ophioglossoides was enabled by fast and accurate calculations of nuclear spin–spin coupling constants (SSCCs) with a relativistic force field (DU8c) parametric method. Two other reported ...
