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 …

Abstract α‐Alkylidene‐substituted δ‐lactones and corresponding γ‐and δ‐lactams constitute
important classes of natural compounds that display diverse biological activities. This review …

The development of a concise total synthesis of (±)‐phyllantidine (1), a member of the
securinega family of alkaloids containing an unusual oxazabicyclo [3.3. 1] nonane core, is …

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

A mild and efficient protocol for the synthesis of p-quinols under aqueous conditions was
developed. The pivotal role of additives in the copper-catalyzed addition of aryl boronic and …

The first SeO2 induced (Z)-selective allylic alcohol formation of dialkyl alkylidenesuccinates
has been demonstrated to accomplish one-step syntheses of several essential butenolides …

An unprecedented Pd (II)-catalyzed decarbonylative C–H/C–C activation and annulation
reaction, which proceeds via intramolecular cyclization, is reported. This reaction of …

A one‐pot tandem process involving hydrolysis, Knoevenagel condensation, Michael
