标 题 :Synthesis of oxalate esters from carbon monoxide and acetals or ketals
发明人：ZEHNER LEE R
权利人:ATLANTIC RICHFIELD CO
摘要:A process for the preparation of oxalate esters by the catalytic oxidative carbonylation of acetals and ketals with carbon monoxide and oxygen-containing gas in the presence of a metal salt catalyst, an amine base and a catalytic amount of an alcohol. Preferably a catalytic amount of particular metal oxidizing salts is employed along with a catalytic amount of an acid or an amine salt compound. Alternatively various counterions and ligands of the metal salt catalysts may be employed.

权利人:BEAUCAGE SERGE L; CIESLAK JACEK; US HEALTH
摘要:Disclosed are O-protected compounds of the formula (I): n nwherein B is an optionally protected nucleobase, and R 1 -R 3 are as described herein, wherein at least one of R 1 -R 3 is —CH 2 —O—Nâ• CHR. The compounds are useful as intermediates in oligonucleotide synthesis. Also disclosed is a method of preparing the compounds from nucleosides via a process comprising conversion of a hydroxyl group to a methylthiomethoxy group, and a method of preparing oligonucleotides such as RNA starting from the compounds. The —CH 2 —O—Nâ• CHR group is stable during oligonucleotide synthesis and can be easily removed after synthesis via, for example, treatment with a base.
