This volume presents research work carried out over a wide front of natural product chemistry. It includes the synthesis of dendrobatid alkaloids, aspidosperma and related alkaloids and some natural products via aliphatic nitro derivatives, cannabinoids, brassinosteroids, quinocarcin and its relate compounds, mannostatins and cyclophellitols and derivatives of grandiflorenic acid and some related diterpines. The text also presents marine cyclic halo ether compounds, oxidative ring transformation furylcarbinols and stereoselective synthesis of C-branded nucleoside analogues. Work on novel polysaccharides from microorganisms and plants, the dereplication of plant-derived natural products, siderophores from fluorescent pseudomonas is also presented.
