Model studies related to the cofactor of the oxomolybdoenzymes Part 5.1 Synthesis of 6-alkenyl- and 6-alkynylpterins
摘要:
6-Alkenylpterin (6) was prepared from pteridine (3a) and (R)-glyceraldehyde acetonide via a Wittig condensation. Treatment of 6 with bromine and then diazabicycloundecane (DBU) produced the corresponding alkyne (8).
