Radical–radical couplings are mostly nearly diffusion‐controlled processes. Therefore, the
selective cross‐coupling of two different radicals is challenging and not a synthetically …

The field in dearomatization of aromatic compounds for the construction of spirocycle
compounds has been developed rapidly over the last two decades and it provides …

A strategy to functionalized spiro [4.5] trienones, by domino silver-catalyzed decarboxylative
acylation or alkylation/ipso-cyclization of N-arylpropiolamides with α-keto acids/alkyl …

Herein we report a cascaded chalcogenation of aryl alkynoates or N-arylpropynamides
using 9-mesityl-10-methylacridinium perchlorate as a visible light photocatalyst to obtain …

Photocatalytic strategies for the preparation of 3-phosphoryl/trifluoromethyl/thiocyanato
azaspiro [4.5] trienones via a radical-initiated cascade annulation reaction of N …

We developed a green method for the synthesis of spiro [4.5] trienones through an
electrochemical oxidative halocyclization with N-aryl alkynamides. This reaction was …

Herein, we report an efficient synthesis of azaspiro [4, 5]‐decanes and azaspiro [4, 5]‐
trienones by the radical cascade spirocyclization of N‐benzylacrylamides or N …

Abstract Radikal‐Radikal‐Kupplungen sind nahezu diffusionskontrollierte Prozesse. Daher
sind selektive Kreuzkupplungen zweier unterschiedlicher Radikale schwierig zu realisieren …

An unprecedented copper-catalyzed ipso-annulation reaction of N-(p-methoxyaryl)
propiolamides with 1, 3-diketones has been developed, which enables the assembly of …

A method for the preparation of 3-alkylated spiro [4.5] trienones via alkylation/ipso-
cyclization of activated alkynes with 4-alkyl-DHPs under transition-metal-free conditions is …
