New cross-coupling reactions and C-H activations for synthesis of modified nucleobase analogues
Krömer, Matouš ; Hocek, Michal (advisor) ; Kotora, Martin (referee)
6 Abstract A novel methodology of construction of 6,7-disubstituted 7-deazapurines by serial of orthogonal cross-coupling reactions was developed. The Liebeskind-Srogl reaction was optimized and the reactivity of a few boronic acids was explored. Library of 3×3 disubstuted analogues of deazapurines was synthesized utilizing this method. In the second part of this work, the scope of direct alkylation of purine derivatives was verified. Keywords purine, 7-deazapurine, orthogonal cross-coupling reactions, C-H activations
