Stereochemical analysis of α1, a mating hormone of the phytopathogen Phytophthora
摘要:
The stereochemistry of alpha 1, the first identified mating hormone of the plant pathogen Phytophthora, has been unknown due to its acyclic flexible nature. Here, two stereogenic centers of alpha 1 are determined to be (3 RS, 15 R) -configuration by NMR analysis of the Mosher's esters of alpha 1 and a synthetic model compound. The information obtained here will be helpful for reducing the burden of the researchers who are trying to synthesize all the possible stereoisomers of alpha 1 to elucidate its full stereochemistry.
