A new simple method for the synthesis of 2‐thioxo‐1,2,3,4,4a,10b‐hexahydro‐5H‐chromeno[4,3‐d]pyrimidin‐5‐ones via acid‐catalyzed condensation of Biginelli products with 1,3‐benzenediols was developed. The diastereoselectivity of this reaction was studied in details. A convenient work‐up procedure providing the major (4R*,4aS*,10bR*) diastereomer from the reaction mixture was found.
Philologists and literary criticists have been researching the foundation of battle scenes in the novel And Quiet Flows the Don by M.A. Sholokhov both from the standpoint of the traditions of literary warfare in Russian literature and from the standpoint of the writer's innovative approach.
