This review highlights a number of additives that can be used to make asymmetric reactions
perfect. Without changing other reaction conditions, simply adding additives can lead to …

The enantioselective synthesis of spirocycles has been a long time pursued dream for
organic chemists. Since the first pioneering efforts of Tamao and coworkers in the …

Abstract An asymmetric catalytic decarboxylative [4+ 2] annulation of 4‐ethynyl
dihydrobenzooxazinones and carboxylic acids has been established by cooperative copper …

Conspectus Total synthesis of natural products has been one of the most exciting and
dynamic areas in synthetic organic chemistry. Nowadays, the major challenge in this field is …

Tetramisole promotes the catalytic asymmetric intramolecular Michael addition−
lactonization of a variety of enone acids, giving carbo-and heterocyclic products with high …

This tutorial review highlights the organocatalytic Lewis base functionalisation of carboxylic
acids, esters and anhydrides via C1-ammonium/azolium enolates. The generation and …

The catalytic cyclocondensation of in situ activated α, β‐unsaturated carboxylic acids was
developed. N‐heterocyclic carbenes efficiently catalyzed the generation of α, β‐unsaturated …

Highly enantioselective [4+ 2] cyclizations of azadienes with in situ generated ketenes were
developed through sequential visible-light photoactivation/isothiourea catalysis, which offers …

Abstract C (1)‐Ammonium enolates are powerful, catalytically generated synthetic
intermediates applied in the enantioselective α‐functionalisation of carboxylic acid …

The ability to rapidly assemble complex carbocyclic frameworks in a catalytic, asymmetric
manner has garnered great interest in recent years. This type of cascade process, which …
