Abstract

Abstract: A convenient protocol for the synthesis of chiral pyran and piperidine ring-fused anthraquinone derivatives has been developed from (R)-2,3-O-cyclohexylidene-glyceraldehyde using sequential applications of enyne metathesis, Diels–Alder reaction and aromatization as key steps.

Abstract

A new route to several hitherto unknown linearly and angularly architectured polycyclic coumarin derivatives has been developed involving tandem applications of three atom economic processes viz. Claisen rearrangement, ring-closing enyne metathesis, and Diels-Alder reactions. [ABSTRACT FROM AUTHOR]
