摘要:Anthranilic acid derivatives exhibiting fungicidal properties and useful as synthesis intermediates have the formula: I wherein R is selected from the group consisting of a hydrogen atom; a -COOR3 group and a -CH2OH group; R1 and R2 are the same or different and selected from the group consisting of a hydrogen atom and alkyl and cycloalkyl groups (provided that R1 and R2 are not both hydrogen atoms), or R1 and R2, together with the nitrogen atom to which they are attached, form a non-aromatic heterocyclic ring structure; R3 is selected from the group consisting of a hydrogen atom and an alkyl group; R4 is selected from the group consisting of a hydrogen atom, a halogen atom and a hydroxyl group; R6 is selected from the group consisting of a hydrogen atom and a halogen atom; and R5 is selected from the group consisting of a hydrogen atom, a halogen atom, and nitro, thiocyano and formyl groups. A process for production of these compounds by self-condensation of a substituted aminocrotonate by phosphorous oxychloride is also disclosed.

标 题:Base-protected nucleotide analogs with protected thiol groups
发明人：HANNA MICHELLE M
权利人:RES CORP TECHNOLOGIES INC
摘要:The present invention is directed to protected thio analogs of the pyrimidine and purine bases for syntheses of DNA and RNA by chemical or enzymatic methods. The subject analogs include reagents suitable for DNA or RNA synthesis via phosphoramidite, H-phosphonate or phosphotriester chemistry as well as reagents suitable for use by RNA and DNA polymerase, including thermostable polymerases employed by PCR or other nucleic acid amplification techniques. Methods of synthesizing the nucleotide analogs are also provided by the present invention. The nucleotide analogs of this invention can thus be incorporated into oligonucleotides or polynucleotides, deprotected and derivatized with a functional group. A method of synthesizing oligonucleotides with a functional group using the subject nucleotide analogs is also provided.
