摘要:The Intramolecular Oxime Olefin Cycloaddition (Iooc) Of Proline And Pipecolinic Acid Derivatives Proceeds Thermally With A High Degree Of Stereoselectivity To Provide A New Route To Functionalized Pyrrolizidines,Indolizidines,Or Quinolizidines. The Ring Closure Proceeds With Simultaneous Stereoselective Introduction Of Three Or Four Stereocenters. Molecular Mechanics Calculations Have Been Refined To Accurately Predict Not Only Which Stereoisomer Is Preferred But Also The Syn And Anti Coupling Constants In These Tricyclic Molecules.

摘要:The present invention relates to chemical linkers and protecting groups, compounds and compositions containing the chemical linkers or protecting groups, and intermediates and processes that can be used to prepare them. The chemical linkers and protecting groups are based on pyrrolidine and piperidine activating groups, which undergo intramolecular cyclisation upon heating with release of carbon dioxide, thereby releasing the organic compound from a substrate. In particular, those chemical linkers and protecting groups are useful in the solid phase synthesis of oligonucleotides according to the following representative schemes.
