Covering: December 1992 to December 2004 The review summarises natural products
containing the 2-pyrone moiety. An emphasis has been placed upon the biological activity …

The pyran ring system is widely present in the animal and plant kingdom and possesses
diverse pharmacological activities. Pyran is a six-membered oxygen heterocycle with two …

Covering: 1968 to June 2010 Tanshinones are a series of abietane diterpenes, isolated
exclusively from Salvia miltiorrhiza and related species. More than 40 tanshinones and their …

Major aspects of the synthetic utility of 1, 3-diketones are reviewed with special emphasis
being placed on the regioselectivity of the transformations. The unsymmetrical 1, 3-diketone …

Abstract A formal [3+ 3] cycloaddition strategy for constructing complex heterocycles is
reviewed here. This formal cycloaddition involves condensation of α, β‐unsaturated iminium …

We have been exploring a strategy for the synthesis of small molecules having properties
that increase the probability of success in all facets of probe-and drug-discovery pipelines …

The most recent achievements in the construction of the 1, 3-diketone moiety are reviewed.
Though both classical and modern approaches to the synthesis of 1, 3-diketones are …

Abstract 2H-Pyran-2-ones are widely present in nature and found as either isolated or in
fused form. Depending on the fusion of benzene ring, pyran can give coumarins …

Evidence is described here to support that a highly stereoselective 6π-electron electrocyclic
ring closure of 1-azatrienes is a key step in formal [3+ 3] cycloaddition or annulation …

The 2-pyrone moiety is present in a wide range of structurally diverse natural products with
various biological activities. The plant biosynthetic routes towards these compounds mainly …
