In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called A useful method for the synthesis of β-2′,3′-dideoxynucleosides via a thioglycoside, published in 1992-07-31, which mentions a compound: 32780-06-6, Name is (S)-5-(Hydroxymethyl)dihydrofuran-2(3H)-one, Molecular C5H8O3, Synthetic Route of C5H8O3.
A series of the protected β-2′,3′-dideoxypyrimidine nucleosides is synthesized stereoselectively by the coupling of Ph 5-O-(tert-butyldiphenylsilyl)-2,3-dideoxy-1-thio-D-glycero-pentofuranoside (I) with silyl derivatives of nucleoside bases in the presence of NBS at -78°. Thus, I was treated with bis(trimethylsilyl)thymine in CH2Cl2 in the presence of 4A mol. sieves and NBS at -78° to give 83% a mixture of β- and α-dideoxynucleosides II and III in the ratio of 3.7:1 resp.
Different reactions of this compound((S)-5-(Hydroxymethyl)dihydrofuran-2(3H)-one)Synthetic Route of C5H8O3 require different conditions, so the reaction conditions are very important.
