Cyclocondensation of alkylhydrazines and .beta.-substituted acetylenic esters: synthesis of 3-hydroxypyrazoles
摘要:
Addition of monosubstituted alkylhydrazines to acetylenic esters with either electron-withdrawing or sterically bulky beta-substituents afforded 1-alkyl-3-hydroxy-5-substituted-pyrazoles 1 as the major regioisomeric product. By comparison, the classical cyclocondensation of alkylhydrazines with beta-keto esters gives the regioisomeric pyrazol-5-ones 2. The reaction solvent employed in these cyclocondensations can have a profound effect on regioisomeric product ratios. Addition of methylhydrazine to 5g in methylene chloride gave regiospecific formation of pyrazolinone 2o, whereas addition in water-methanol mixtures afforded hydroxypyrazole 1o as the major product. Structural assignment of regioisomers 1 and 2 are based on C-13 NMR chemical shifts, long-range heteronuclear coupling constants, and comparisons with regiochemically known hydroxypyrazoles and/or pyrazolinones. Additions of acetylene 5b to 1,1-dimethylhydrazine afforded either acyclic enehydrazone 12 or pyrazolium betaine 13 depending on the reaction conditions.
The invention relates to substituted dihydropyrazolo pyrazine carboxamide derivatives and to processes for their preparation, and also to their use for preparing medicaments for the treatment and/or prophylaxis of diseases, in particular cardiovascular disorders, preferably thrombotic or thromboembolic disorders, and diabetes, and also urogenital and ophthalmic disorders.
