Fullerene derivatives resulting from an unexpected Diels-Aldercycloaddition have been obtained by reaction of trans-2-stilbenecarboxaldehyde derivatives with N-methylglycine and C60.

A simple, efficient and highly selective one-pot approach for the synthesis of biologically important novel dispiro heterocycles assembling three pharmacophoric moieties such as piperidinone, 1,3-indanedione, and pyrrolidine in a single molecular framework by means of three-component reaction between ninhydrin, sarcosine, and 1-benzyl/methyl-3,5-bis[(E)-arylidene]-piperidin-4-one is reported in task-specific

A facile one-pot synthesis of pyrrolidinyl-spirooxindole grafted 3-nitrochromanes has been accomplished by 1,3-dipolar cycloaddition (1,3-DC) reaction of 3-nitrochromenes with azomethineylides generated in situ from isatin and secondary amino acids. The regio- and stereochemical outcome of the cycloaddition reaction was ascertained by X-ray crystallographic analysis.

The effect of nonionic and anionicmicellesupon the stability of 3‐hydroxy‐carbofuran in basic media has been studied. The presence of micelles in the reaction medium implies a large inhibition of the basic hydrolysis of 3‐hydroxy‐carbofuran, due to the association of 3‐hydroxy‐carbofuran with the micellar core. The kinetic constants for the basic hydrolysis in these microheterogeneous media have

The total synthesis of the marine natural product naamidine J and a rapid structure modification toward itsderivatives were achieved on the basis of several rounds of structure-relationship analyses of their tumor immunological activities. These compounds were tested for programmed death-ligand 1 (PD-L1) protein expression in human colorectal adenocarcinoma RKO cells. Among them, compound 11c was
