标题:α-羟基缩醛的有机催化对映选择性环糊精重排为α-烷氧基酮
摘要:我们报告了史无前例的α,α-二取代的α-羟基缩醛的有机催化对映选择性酰基肌醇重排.在催化量的手性二元醇衍生的氮存在下-三氟磷酰胺,α-羟基缩醛重排成α-烷氧基酮,具有高至高收率和高对映选择性.有人建议在原位反应生成的氧碳鎓离子和手性磷酰胺阴离子之间形成离子对,这是手性高效转移的原因.发现了从相应的α-烷氧基酮中除去环己基和环戊基的条件,这证明了它们作为羟基保护基团的潜在通用性.还记录了重排产物转化为对映体富集的α-羟基酮,1,2-二醇,β-氨基醇和1,4-二恶烷的过程.

摘要:The present invention relates to monomers of formula (I) having a nitrogen atom that can be protonated at relatively low pH values (e.g., less than pH 9.5 or less than pH 9), polymers containing monomeric units derived from these monomers, anion exchange separation articles having the polymers grafted to a porous substrate, and methods of using the anion separation articles to separate mixtures of materials with different ionic content are described. Advantageously, the anion exchange separation articles can be used to separate biomaterials that cannot be subjected to high pH conditions (e.g., greater than 9 or 9.5) and/or to high ionic strength conditions (e.g., greater than 0.5M or 1M).

权利人:UNIV SOUTHERN MISSISSIPPI
摘要:A process for synthesizing ethers of alkyl alpha(hydroxymethyl)-acrylate by reacting alkyl acrylate and formaldehyde in the presence of a DABCO catalyst. The ethers may be used as cross-linking agents for thermoplastic polymers. Further, these ethers in turn enable synthesis of cyclopolymers that may show promising biological activity.
