Synthesis of (S,5Z,8E,10E)-12-Hydroxyheptadeca-5,8,10-trienoic Acid (12S-HHT) and its Analogues
摘要:
Natural 12S-HHT and its analogues were synthesized for study of structure and activity relationship toward the BLT2 receptor. The Suzuki-Miyaura coupling was used for construction of the 8E, 10E-diene moiety of 12S-HHT and analogues of (12R)- and 12-keto-types, whereas Wittig reaction was used for the synthesis of (8Z)- and (8Z, 12R)-isomers.

Therefore, researchers have tried to develop efficient catalytic systems to access this scaffold. This work reports the synthesis of various azaoxa- and diazaspirocycles from alkynes bearing two pendant nitrogen- and oxygen-based nucleophiles under silver catalysis.
