Abstract β‐Keto amides are a versatile class of compounds that find wide applications in
organic chemistry owing to the juxtaposition of multiple reaction sites within their molecular …

Aminolysis of esters by using the organocatalyst 1, 5, 7-triazabicyclo [4.4. 0] dec-5-ene
(TBD) is reported. Secondary and tertiary amides were synthesized from alkyl or aryl esters …

In this paper, a NaOtBu-mediated synthesis approach was developed for direct amidation of
unactivated esters with amines under transition-metal-free and solvent-free conditions …

Abstract RhII‐catalyzed intermolecular [3+ 2] cycloaddition of 2 H‐azirines with N‐sulfonyl‐
1, 2, 3‐triazoles is disclosed, in which a series of fully functionalized pyrroles is produced via …

Many physiological functions, such as cell differentiation, proliferation, muscle contraction,
neurotransmission and fertilisation, are regulated by changes of Ca 2+ levels. The major Ca …

The synthesis of a series of benzisothiazolone derivatives starting from the readily available
methyl thiosalicylate is presented. The key cyclization step features the formation of a N …

A fast and efficient protocol for the formation of amides from low nucleophilic amines and
esters in flow is described. Products were obtained in good to excellent yields and with the …

This study reports the first example of a heterogeneous catalytic system for the direct
amidation of various esters with amines. Of 25 types of catalyst, Nb2O5 shows the highest …

Magnesium methoxide (Mg (OCH3) 2) and calcium chloride have been shown to facilitate
the direct aminolysis of esters by ammonia to primary amides. Methyl, ethyl, isopropyl, and …

A sustainable and cost‐effective protocol has been reported for the synthesis of amide
bonds from unactivated esters and non‐nucleophilic amines promoted by potassium tert …
