Paragraph 0054-0080, (2020/07/21)
The invention relates to a synthesis method of 4-iodine-1H-pyrrole-2-formaldehyde, and the synthetic route is shown as the specification. The synthesis method includes: in a selected reaction solvent,reacting 1H-pyrrole-2-formaldehyde (1) with elemental iodine under the action of a selected inorganic base to generate 4-iodine-1H-pyrrole-2-formaldehyde (2); wherein the reaction solvent is any oneof N, N-dimethylformamide, N, N-dimethylacetamide and N-methyl pyrrolidone, and the inorganic base is one of lithium hydroxide, sodium hydroxide and potassium hydroxide.

To develop unnatural base pairs that function in replication, we designed 4-propynylpyrrole-2-carbaldehyde (designated as Pa′) and synthesized the nucleoside derivatives of Pa′. The base pairing of Pa′ with the partner, 9-methylimidazo[(4,5)-b]pyridine (Q), was compared to that of pyrrole-2-carbaldehyde (Pa), which was previously developed as a specific pairing partner of Q. The thermal stability of a DNA duplex containing the Q-Pa′ pair and the incorporation efficiency of the Pa′ substrate (dPa′TP) into DNA opposite Q by the Klenow fragment of Escherichia coli DNA polymerase I were improved, in comparison with those of the Q-Pa pair. These improvements result from the increased hydrophobicity and stacking stability of Pa′ by the introduction of the propynyl group to Pa, providing valuable information for the further development of unnatural base pairs toward the expansion of the genetic alphabet.
THALLIUM AND MERCURY IN PYRROLE CHEMISTRY. USE OF C-THALLIATED AND C-MERCURIATED PYRROLE DERIVATIVES FOR SELECTIVE RING FUNCTIONALISATIONS via ipso-DETHALLIATION AND -DEMERCURIATION REACTIONS

, p. 771 - 774 (2007/10/02)
The use of C-thalliated and C-mercuriated pyrroles to achieve selective introduction of various functional groups in a β position is described.High yields of hardly accessible pyrrole derivatives (such as nitropyrrole) can thus be obtained.
