标题:Method for the Synthesis of Ionizable Lipids Using a Doubly Alkylated Intermediate
发明人：SAADATI FARIBA; TRAN HUY; CIUFOLINI MARCO; ATMURI N D PRASAD
权利人:NANOVATION THERAPEUTICS INC
摘要:Provided herein is a method for the preparation of ionizable, cationic amino lipids using a doubly alkylated nucleophilic intermediate to produce a ketone. The ketone, or a corresponding alcohol, is subjected to one or more synthesis steps to add an ionizable moiety thereto. The method can be advantageously employed for the synthesis of unsymmetrical analogues of the above lipids that would be considerably more difficult to make by alternative strategies. The method can also be used to prepare symmetrical ionizable, cationic amino lipids with fewer steps and/or with the use of fewer hazardous chemicals than known synthesis methods.

摘要:The invention provides a method for preparing an optically active alcohol comprising the step of reacting a ketone compound with a hydride reagent in the presence of an optically active metal compound. The resulting optically active alcohols are useful as intermediates for the synthesis of physiologically active compounds such as drugs and pesticides, functional materials such as liquid crystals, and raw materials for synthesis in fine chemistry. A novel optically active cobalt (II) complex useful as a catalyst is also provided.

标 题 :Process for the preparation of 3, 4-dihydroxybutanoic acid and derivatives thereof from substituted pentose sugars
发明人：HOLLINGSWORTH RAWLE I
权利人:UNIV MICHIGAN STATE
摘要:A process for the preparation of 3,4-dihydroxybutanoic acid (I) and 3-hydroxy-γ-butyrolactone (V) thereof from a 3-leaving group substituted pentose source is described. In particular, the process relates to the synthesis of (R)-3,4-dihydroxybutanoic acid and (R)-3-hydroxy-γ-butyrolactone from a 3-leaving group substituted L-pentose sugars. The process uses a base and a peroxide to convert the pentose source to the chiral 3,4-dihydroxybutanoic acid compound. The chiral 3,4-dihydroxybutanoic acid can be further converted to 3-hydroxy-γ-butyrolactone by acidification. The chiral compound is useful as a chemical intermediate to the synthesis of various drugs and other products.
