标 题 :Synthesis of n-glycosylated compounds with the use of a mild, iodine-catalyzed reaction
发明人：KOREEDA MASATO; HOUSTON TODD A
权利人:UNIV MICHIGAN
摘要:The invention concerns N-glycosylated derivatives of nitrogen nucleophile compounds. The invention also concerns a mild, cost effective, stereoselective, regioselective, and generally applicable method for the preparation of N-glycosides by N-glycosylation of azide and amide nucleophile compounds. The method employs iodine in a catalytic amount that uniquely does not pose an environmental hazard. The invention provides efficient access to key intermediates for the synthesis inter alia of analogs of AZT and DDI and for the synthesis of conventional N-nucleoside antibiotic drugs and their novel N-glycosylated analogs.

摘要:The invention herein disclosed provides for methods for the synthesis of polymers from monomers. In particular the method provides for the synthesis of polynucleotides from mononucleotides in the absence of catalytic enzymes. The method comprises providing an aqueous solution having a plurality of phospholipid molecules and monomer molecules; subjecting the aqueous solution to fluctuating temperature conditions; subjecting the aqueous solution to fluctuating cycles of drying and hydrating conditions; subjecting the aqueous solution to fluctuating [H + ] conditions; the fluctuating conditions thereby allowing formation of a chemical bond between at least two monomers to create a polymer. The invention is of particular use in the fields of molecular biology, structural biology, cell biology, molecular switches, molecular circuits, and molecular computational devices, and the manufacture thereof.

标题 :Processes for high-yield diastereoselective synthesis of dideoxynucleosides

摘要:The present invention relates to methods for substantially enhancing the stereoselective synthesis of β-anomeric nucleoside analogs. In methods according to the present invention, the introduction of a phenylseleno group onto a blocked lactone sugar precursor may be selected so that the desirable phenylseleno substituent is introduced on the side of the blocked lactone away from the blocking group. This stereospecific introduction of the phenylseleno group in sugar precursor allows the synthesis of nucleoside analogs and in particular, 2',3',-dideoxy- and 2',3'-dideoxy-2',3'-didehydronucleoside analogs in very high yield. In certain preferred embodiments, the preferred phenylseleno blocked lactone is obtained in an amount representing approximately 90% or more of the total amount of the stereoisomers obtained. In even more preferred embodiments, the amount of the preferred stereoisomer is at least 95%, even more preferably at least about 97% of the total amount of phenylseleno blocked lactone produced.
