This comprehensive review summarizes the published literature data concerning the chemistry of α‐enolazible alkynones, also denoted aliphatic or C‐H active alkynones, where an alkyl group is adjacent to the carbonyl function, from the first example in 1949 to the present day. Starting from a historical perspective, the reader will be introduced to the recent achievements and future challenges in this

Catalytic dearomatization of arenols is an uphill task that can serve as a powerful method to construct C‐C bonds with unsaturated coupling partners. Herein, a simple and efficient strategy for coupling naphthols with allylic alcohols is reported. A single Ru(II) pincer catalyzed coupling of naphthols with primary allylic alcohols led to the formation of benzo(f)chromanes, whereas the use of secondary

Difuropyridines have been prepared from aldehydes and chitin‐derived 3‐acetamidofuran (3AF) under acid‐catalyzed conditions. Difuropyridines were comprehensively synthesized for the first time. The synthesized difuropyridines can be applied to prepare fluorescent probe analogs or catalyze decarboxylative reactions as photocatalysts.

An efficient Rh(III)‐catalyzed C‐H bond activation/cyclization of 2‐arylbenzimidazoles with CF3‐imidoyl sulfoxonium ylides has been achieved, yielding diverse CF3‐ and amino‐disubstituted 5,6‐dihydrobenzoimidazo[2,1‐a]isoquinolines, which could undergo a deaminative hydroxylation to access CF3‐ and hydroxy‐disubstituted 5,6‐dihydrobenzoimidazo[2,1‐a]isoquinolines under Sc(OTf)3 catalyst. This developed

The bicyclo[3.3.1]nonane ring represents an attractive yet challenging synthetic targets in the field of organic synthesis, especially in a stereocontrolled fashion. Over the past two decades, organocatalysis has emerged as an enabling technology for the facile construction of enantioenriched molecules with remarkably increasing complexity and diversity, and a myriad of chiral architectures containing

A concise and practical sustainable strategy for modular access to isoquinoline‐fused benzo[f][1,3]oxazepine derivatives through a formal [4+3] annulation of commercially available salicyaldehydes with isoquinolinium salts has been developed. The reactions proceeded through the formation of two new bonds (C=C and C‐O) and a seven‐membered heterocyclic ring in one pot. Remarkably, use of simple NaHCO3

We have developed a synthesis for tetrahydro‐β‐carbolines involving cascade sigmatropic rearrangements. The substrates were conveniently prepared from parent anilines via a [2,3]‐sigmatropic rearrangement and cyanomethylation. Silver‐mediated decyanation afforded the corresponding iminium cation, which underwent a cascade consisting of an aza‐Cope rearrangement, an aza‐oxa‐Cope rearrangement, an aromatization
