Abstract
Marine natural products (MNPs) containing pyrone rings have been isolated
from numerous marine organisms, and also produced by marine fungi and bacteria, particularly,
actinomycetes. They constitute a versatile structure unit of bioactive natural
products that exhibit various biological activities such as antibiotic, antifungal, cytotoxic,
neurotoxic, phytotoxic and anti-tyrosinase. The two structure isomers of pyrone ring are γ-
pyrone and α-pyrone. In terms of chemical motif, γ-pyrone is the vinologous form of α-
pyrone which possesses a lactone ring. Actinomycete bacteria are responsible for the production
of several α-pyrone compounds such as elijopyrones A-D, salinipyrones and violapyrones
etc. to name a few. A class of pyrone metabolites, polypropionates which have
fascinating carbon skeleton, is primarily produced by marine molluscs. Interestingly, some
of the pyrone polytketides which are found in cone snails are actually synthesized by actinomycete bacteria.
Several pyrone derivatives have been obtained from marine fungi such as Aspergillums flavus, Altenaria sp.,
etc. The γ-pyrone derivative namely, kojic acid obtained from Aspergillus fungus has high commercial demand
and finds various applications. Kojic acid and its derivative displayed inhibition of tyrosinase activity and, it is
also extensively used as a ligand in coordination chemistry. Owing to their commercial and biological significance,
the synthesis of pyrone containing compounds has been given attention over the past years. Few reviews
on the total synthesis of pyrone containing natural products namely, polypropionate metabolites have been reported.
However, these reviews skipped other marine pyrone metabolites and also omitted discussion on isolation
and detailed biological activities. This review presents a brief account of the isolation of marine metabolites
containing a pyrone ring and their reported bio-activities. Further, the review covers the synthesis of marine
pyrone metabolites such as cyercene-A, placidenes, onchitriol-I, onchitriol-II, crispatene, photodeoxytrichidione,
(-) membrenone-C, lihualide-B, macrocyclic enol ethers and auripyrones-A & B.

Abstract
The Stille coupling between organostannanes and organohalides is an effective catalytic method for organic synthesis. Despite the ample amount of published results in this area, finding the optimal conditions for this transformation is often not straightforward. It was observed that this reaction could be accelerated with improved efficiency by the addition of a Cu(i) salt and fluoride. This review summarises the application of this simple protocol in the synthesis of natural products, their analogues and other biologically active molecules, from 2004 to 2018.

Abstract
Novel Kv1.3 blocking immunosuppressants, (-)-candelalides A, B and C, were efficiently synthesized for the first time in a convergent and unified manner starting from (+)-5-methyl-Wieland-Miescher ketone. The synthetic method involved the following key steps: i) a strategic [2,3]-Wittig rearrangement of a stannylmethyl ether to install the stereogenic center at C9 and the exo-methylene function at C8 present in the decalin portion; ii) a straightforward coupling of a trans-decalin portion (BC ring) and a gamma-pyrone moiety through the C16-C3' bond to assemble the requisite carbon framework; and iii) a construction of a characteristic di or tetrahydropyran ring (A ring) by internal nucleophilic ring closure of a hydroxy aldehyde or a hydroxy epoxide. The present total synthesis has fully established the absolute configuration of these natural products.

Abstract
An overview of marine natural products synthesis during 2005 is provided. In a similar vein to earlier installments in this series, the emphasis is on total syntheses of molecules of contemporary interest, new total syntheses, and syntheses that have resulted in structure confirmation or stereochemical assignments.

Abstract
Mollusks of the Sacoglossa order contain a variety of polypropionate metabolites that are characterized by a pyrone chromophore, such as cyercene A and 9,10-deoxytridachione. Most often the pyrone is a 2-methoxy-gamma-pyrone but occasionally is a 4-methoxy-alpha-pyrone or hydropyrone. Members of this class of metabolites have been shown to undergo photochemical reactions of biosynthetic importance. An example is the photochemical conversion of 9,10-deoxytridachione to photodeoxytridachione, which has been observed in several mollusks. In this report, a series of gamma-pyrones and their alpha-pyrone analogs were synthesized and analyzed for photosensitizing activity. In all cases studied, the gamma-pyrone was a more efficient triplet sensitizer than the corresponding alpha-pyrone. Included in this set of molecules was the Sacoglossan metabolite cyercene A and its alpha-pyrone isomer. When irradiated in the presence of oxygen, cyercene A produced singlet oxygen at significantly higher rate than the corresponding alpha-pyrone isomer. Furthermore, the photoisomerization of cyercene A was quenched by piperylene with con-committant isomerization of the piperylene indicating that the isomerization proceeded through a triplet excited state. In contrast, the isomerization of the alpha-pyrone analog was not quenched. The implications of these photochemical results in terms of the biosynthesis and biological activity of Sacoglossan polypropionate metabolites are discussed.
