inexpensive d-galactose from the chiralpool, l-deoxyribose, l-ribose and their derivatives were synthesized via mild reaction conditions. During the synthesis of l-deoxyribose, the key deoxygenation of the 2-hydroxy group of 3,5-O-dibenzyl-methyl-l-arabinofuranoside was performed by reduction of the corresponding triflate with tetrabutylammonium borohydride in high yield. During the synthesis of l-ribose, the
A protocol for visible-light-induced C–H acylation selectively at the C6 position of purine nucleosides with aldehydes under photocatalyst-free conditions was established herein. This protocol allows the green, mild, and efficient functionalization of various purine nucleosides with a broad range of alkyl and aryl aldehydes.
