Evapotranspiration (ET) is crucial for the water and carbon cycles of ecosystems, and accurate characterization of ET processes is essential for understanding regional water cycle mechanisms and ecohydrological dynamics. However, limitations in observational data and conventional modeling frameworks continue to constrain the …

]quinazolin-3,6-dione core is described through an original strategy involving the pivotal cyclocondensation of an electrophilic homoserine lactone intermediate. The alkylidene group was spontaneously installed by autoxidation during the cyclocondensation process, while the propionamide side chain was introduced through the nickel-catalyzed aminocarbonylation of …

The total synthesis of cyclotripeptidic natural products possessing a central piperazino[2,1-b]quinazolin-3,6-dione core is described, through an original strategy involving the pivotal cyclocondensation of an electrophilic homoserine lactone intermediate. The alkylidene group was spontaneously installed by autooxidation during the cyclocondensa-tion process, while the …

Total syntheses of (+)-cinereain and (-)-janoxepin, two fungal cyclotripeptides featuring a complex heterocyclic core and interesting phytotoxic and antimalarial activities, have been achieved in a convergent manner. A key step in this synthesis is a one-pot cascade initiated by the cyclocondensation of …

The introduction of substituents on bare heterocyclic scaffolds can selectively be achieved by directed C-H functionalization. However, such methods have only occasionally been used, in an iterative manner, to decorate various positions of a medicinal scaffold to build chemical libraries. We herein …

The retro‐Claisen [3,3]‐sigmatropic rearrangement of γ,δ‐enoyl compounds allows the formation of a C–O bond while breaking a C–C bond in a concerted process. It is rarely observed with acyclic substrates. However, when the alkene and carbonyl groups are tethered by a cyclopropane, …
