They have been used for the imaginative synthesis of a wide range of compounds, and have been found to be effective chiral auxiliaries which enable the introduction of a range of functionalities in a highly enantioselective manner. In a subject dominated by volumes at research and professional level, this book provides a broad understanding of the use of carbohydrates in organic synthesis, at postgraduate student level. Emphasis is placed on retrosynthetic analysis, with discussion of why a particular synthetPostgraduate chemistry series.CarbohydratesSynthesisOrganic compoundsSynthesisCarbohydratesSynthesis.Organic compoundsSynthesis.547.2547/.780459Boons Geert-Jan877768Hale Karl888208MiAaPQMiAaPQMiAaPQBOOK996197691603316Organic synthesis with carbohydrates1984077UNISA00986nam0 22002531i 450 UON0040605720231205104718.86020120301d1974 |0itac50 baitaIT|||| |||||Aspetti operativi del management(an in basket training exercise)Cabot L.
