摘要：The DMAP-catalyzed [4＋2] cycloaddition of α,β-unsaturated carboxylic acids with ketones furnishing α,β-unsaturated δ-lactones in good yields （up to 80%） is described, which is the first example of remote -C（sp^3）-H activation of α,β-unsaturated carboxylic acids facilitated by DMAP, a pyridine-based catalyst.
