—— | 3-(2-ethoxy-2-oxoethyl)-2-[(1-(octadecyl)-1H-1,2,3-triazol-4-yl)methyl]sulfanyl-4-oxo-3,4,5,8-tetrahydro-spirobenzo[b]thieno[2,3-d]-pyrimidine-7(6H),1'-cyclohexane | 1427557-35-4 | C40H63N5O3S2 | 726.104 |
A mild and versatile method based on Cu(I)-catalyzed [3+2] cycloaddition (Meldal-Sharpless reaction) was developed to tether biomolecules, such as monosacharides or lipophylic azides, to alkyne functions of spirobenzo[b]thieno[2,3-d]pyrimidine-1´-cyclohexane. The reactions are highlighted by their modularity and high efficiency with excellent yields in most cases. The products are interesting precursors for a variety of applications.
