3'-5'- or 2'-5'-linked diribonucleotides having definite sequences have been synthesized by an one-flask procedure utilizing the cyclic phosphorylation of the cis-glycol in the ribonucleosides with aminophosphordichloridites.
Method for preparing 2-hydroxy-4-methyltetrahydropyran

Paragraph 0070; 0072, (2017/07/21)
The invention relates to a method for preparing 2-hydroxy-4-methyltetrahydropyran (MHP) from using 3-methyl-3-buten-1-ol (IPEA) as a raw material under the catalysis of a rhodium compound and a tertiary phosphine ligand. After a reaction is finished, water extraction is performed for separating products from catalysts, wherein the rhodium catalyst and the tertiary phosphine ligand are reserved in an organic phase, the products are reserved in an aqueous phase, the conversion rate of IPEA can be as high as 99.7%, and the MHP selectivity of the products can be up tp 85.9%. The method solves the difficult problem that the costly rhodium catalyst is difficult to recover in a hydroformylation reaction process, and is favorable for industrial application.
