    Stereoselective Synthesis of β-Anomeric 4‘-Thiaspirocyclic Ribonucleosides Carrying the Full Complement of RNA-Level Hydroxyl Substitution
    摘要:
    Stereoselective syntheses of a group of 4'-thiaspirocyclic ribonucleosides featuring both pyrimidine and purine classes and both possible configurations at C-5' are described. Use is made of the Pummerer reaction of substrates carrying an a-oriented 2,4-dimethoxybenzoyloxy substituent at C-2 in order to gain reliable stereocontrol via neighboring group participation. Irrespective of the S or R configuration of the pivotal sulfoxide intermediates, the nucleobase is captured from the beta-face. The competing process is formation of unsaturated sulfoxides, presumably via competing E2-type elimination. Although differences in reactivity between the two stereoisomeric series were noted, the common route has successfully given rise for the first time to desirable beta-anomeric sulfur-containing spiroribonucleosides with minimum formation of the alpha-anomers.

    A stereospecific synthesis of 2′-deoxy-2′,2′-difluorocytidine (gemcitabine), a potential anticancer agent, is described. The stereoselectivity was accomplished via two diastereoselective crystallizations, i. e. the crystallization of the key intermediate, difluororibonolactone 2a, and the crystallization of the hydrochloride salt of gemcitabine 16b from the anomeric mixture. Because of the availability of 2a in large quantities, other 2′-deoxy-2′,2′-difluoropyrimidine nucleosides such as 2′-deoxy-2′,2′-difluorouridine (19) were synthesized for structure-activity relationship studies.

The glycosidation reactions of these 4-thioglycals were carried out, in the presence of either PhSeCl or NIS, by using silylated derivatives of uracil, thymine, cytosine, and N(6)-benzoyladenine. Among the three 4-thioglycals, 11 was found to be an excellent glycosyl donor, forming
