Synthesis of derivatives of methyl 3-deoxy-3-C-formyl-α-d-arabino-pentofuranoside
摘要:
Methyl 2,3-anhydro-alpha-D-lyxofuranoside and some 5-substituted derivatives react with 2-lithio-1,3-dithiane and phenylthiomethyl-lithium at both positions of the epoxide ring. but mainly at C-3. The ratio of the adducts is affected by the nature of the 5-substituent. Appropriate desulphuration reactions of the dithioacetal and sulphide functions in the adducts gave derivatives of methyl 3-deoxy-3-C-formyl-alpha-D-arabino-pentofuranoside.
