Abstract: | Synthesis of the metabolically stable analogue of thiazole-4-carboxamide adenine dinucleotide (beta-methylene-TAD) was achieved via the sequential monodeprotection of tetrabenzyl methylenebis(phosphonate) after two rounds of Mitsunobu esterifications with the corresponding nucleoside components, tiazofurin and adenosine. |
