The amount of research activity concerning α‐methylene‐γ‐butyrolactones and α‐alkylidene‐
γ‐butyrolactones has increased dramatically in recent years. This Review summarizes the …

The gem-difluoroalkene moiety is an ideal carbonyl bioisostere in medicinal chemistry, but
efficient synthesis of β-gem-difluoroalkene esters remains challenging so far. Herein, we …

Radical cyclization reactions are among the most powerful and versatile methods for the
construction of mono‐and polycyclic systems. The advantages these reactions offer to the …

Seit einigen Jahren erlebt die Forschung an α‐Methylen‐γ‐butyrolactonen einen enormen
Aufschwung. Diese Übersicht beschreibt die Strukturen, die biologische Aktivität und die …

We report a full account of our work toward the total synthesis of pseudolaric acid B (1a), a
diterpene acid isolated from the bark of Pseudolarix kaempferi Gordon (pinaceae) …

In recent decades, difunctionalization of alkenes has received considerable attention as an
efficient and straightforward way to increase molecular complexity. However, examples of …

An alkoxycarbonyl radical cyclization–cross‐coupling cascade has been developed that
allows functionalized γ‐butyrolactones to be prepared in one step from simple tertiary …

Tandem radical cyclizations of suitably substituted N-aryl thiocarbamates, thioamides, and
thioureas are induced by exposure to tris (trimethylsilyl) silane (TTMSH) and UV light and …

Visible-light photoredox-catalyzed fragmentation of methyl N-phthalimidoyl oxalate allows
the direct construction of a 1, 4-dicarbonyl structural motif by a conjugate addition of the …

Natural inspiration: A concise total synthesis of (±)‐stemoamide was completed in eight
steps with a 37% overall yield. A bioinspired N‐acyliminium ion cyclization and an …
