摘要:In one aspect, the disclosure relates to a facile strategy to introduce electron-deficient aryl sulfate diesters to silylated hydroxyl groups of carbohydrates and amino acids, among other substrates, wherein selective hydrolysis and the removal of an electron-deficient aromatic group allows for the efficient generation of sulfated carbohydrates, peptides, and other compounds. The incorporation of electron-deficient aryl sulfate diesters in the early stage of the synthesis of glycans, peptides, and the like, disclosed herein avoids time-consuming protecting group manipulations, simplifies the purification of sulfated products, and improves the overall yield and efficiency. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

标题:Synthesis of cyclic organic compounds and metallocenes
发明人：PADILLA-ACEVEDO ANGELA I; KUHLMAN ROGER L
权利人:UNIVATION TECH LLC
摘要:A method comprising synthesizing a cyclic organic compound via reaction of an unsubstituted or substituted cyclopentene with an unsubstituted or substituted acrylic acid in the presence of phosphoric and/or sulfonic acid reagent to make the cyclic organic compound. Also, a method of synthesizing a ligand for a transition metal, and a related substituted ligand-metal complex and catalyst, from the unsubstituted or substituted cyclopentene and unsubstituted or substituted acrylic acid. Also, the cyclic organic compound, ligand, and substituted ligand-metal complex and catalyst synthesized thereby. Also a method of polymerizing an olefin with the catalyst to give a polyolefin, and the polyolefin made thereby.
