Table 3. Decarboxylative Conjugate Addition: Scope of Carboxylic Acid Fragment^a.

^aReaction performed using the optimized conditions from Table 1 (see SI). The cited yields are isolated. Ratios of diastereoisomers determined by ¹H NMR analysis are between 1 and 1.5:1.

^bReaction performed using 34 W blue LED, instead of 26 W fluorescent light.

^cCyclopentanecarboxylic acid and octanoic acid also worked under the reaction conditions, affording the corresponding products in ≥58% yield with 1,4-dioxane as a solvent.

^dReaction concentration is 0.2 M.
