Advances in Organic Synthesis is a book series devoted to the latest advances in synthetic approaches towards challenging structures. The series presents comprehensive reviews written by eminent authorities on different synthetic approaches to selected target molecules and new methods developed to achieve specific synthetic transformations or optimal product yields. Advances in Organic Synthesis is essential for all organic chemists in academia and the industry who wish to keep abreast of rapid and important developments in the field. This volume presents the following reviews: Electroluminescent polymers - a review on synthesis from organic compounds. Remarkable advances in the asymmetric synthesis of biologically active natural compounds from the advent of chiral auxiliaries. The chemistry of ynamides and their application in organic synthesis Carbon-heteroatom bond formation for medium ring heterocyclesTin(ii) salts: versatile and efficient lewis acid catalysts in reactions to add value to the glycerol and terpenic alcohols(E)-n-methyl-1-(methylthio)-2-nitroethenamine (nmsm) as a versatile ambiphilic synthon in organic synthesis
