Abstract:
The synthesis of methyl 2-formyl-6-(methoxymethyl)furo[2,3-b]pyrrole-5-carboxylate (1d) is described. The reactions of methyl 2-formylfuro[2,3-b]pyrrole-5-carboxylates 1a-1d with malononitrile afforded methyl 2-(2,2-dicyanovinyl)furo[2,3-b]pyrrole-5-carboxylates 3a-3d, with methyl cyanoacetate methyl 2-[2-cyano-2-(methoxycarbonyl)vinyl]furo[2,3-b]pyrrole-5-carboxylates 4a-4d and with 2-furylacetonitrile methyl 2-[2-cyano-2-(2-furyl)vinyl]furo[2,3-b]pyrrole-5-carboxylates 5a-5d.

Abstract:
Abstract Synthesis of methyl 4H-furo[3,2-b]pyrrole-5-carboxylate is taken place in two step synthesis. Vilsmeier-Haack reaction of 4H-furo[3,2-b]pyrrole-5-carboxylate 1 led to methyl 2-formyl-4H-furo[3,2- b]pyrrole-5-carboxylate 4, which served as starting compound for synthesis of furo[3,2-b]pyrrole-2- aldoxime 5 and methyl 2-[(4-oxo-2-thioxo-1,3-thiazolidin-5-ylidene)methyl]-4H-furo[3,2-b]pyrrole-5- carboxylate 7. The hydrazinolysis of 1 was prepared by carbohydrazide 2, which subsequently reacted with aldehydes to form of derivatives 3. Pyrazole derivatives 11 were prepared by the reaction

Abstract:
A reinvestigation of the cyclization of pyrrol-2-yl phenacyl sulfides in polyphosphoric acid has shown that the major product is a thieno[3,2-b]pyrrole, where rearrangement of the sulfur substituent from position 2 to position 3 has preceded cyclization. When TiCl4 is used as cyclocondensation reagent minimal rearrangement is observed and the product obtained is either a thiazolo[3,2-a]pyrrole when the pyrrole nitrogen is unsubstituted, or a thieno[2,3-b]pyrrole where an N-substituent is present.

Abstract:
Prostate cancer (PCa) is the second most frequently diagnosed malignancy, as well as a leading cause of cancer-related mortality in men globally. Despite the initial response to hormonal targeted therapy, the majority of patients ultimately progress to a lethal form of the disease, termed as castration-resistant prostate cancer (CRPC), which currently lacks curative therapeutic options and is associated with poor prognosis. Therefore, the development of novel treatment modalities for PCa is urgently needed. Chalcones, also known as 1,3-diphenyl-2-propen-1-ones, are among the highly attractive
