	The iron-catalyzed hydrogen atom transfer (HAT)-initiated Dowd-Beckwith rearrangement presents a new approach for synthesizing cyclic and spirocyclic quaternary carbons from readily available beta-keto esters and cyclic diketones with high yields. This reaction proceeds in a stereocontrolled manner, enabling the formation of synthetically valuable cyclic ketones with two contiguous stereocenters, including quaternary centers. This transformation introduces an innovative bond disconnection strategy for ring-contraction reactions. Additionally, a short formal synthesis of perhydrohistrionicotoxin was efficiently achieved using this methodology.</p>

	abstract = {<p>A simple and efficient organocatalytic method has been developed to access {\textquoteleft}{\textquoteleft}readily modifiable{\textquoteright}{\textquoteright} amides, including bench-stable N-acyl saccharin and various activated amides, from aldehydes by using CTAB- t BuOOH. A wide range of aromatic and aliphatic acyl saccharin are obtained from their respective aldehydes with moderate to good yields. The approach can be similarly applied toward the formation of N-acyl imidazole, N-acyl benzimidazole, N-methoxy-N-methylamide (Weinreb amide), N-ethyl-N-phenylbenzamide, N-acyl morpholine, N-acyl valerolactam, and N-acyl caprolactam. These compounds are frequently applied as reagents in organic transformations, including acyl coupling, decarbonylative coupling, radical coupling, and coupling that is free from transition metals, enabling the synthesis of new C-C, C-N, C-O, C-S, C-P, and C-B bonds.</p>
