Configurational assignment of brassinosteroid sidechain by exciton coupled circular dichroic spectroscopy

[摘要] A microscale method was developed to determine the sidechain configuration of brassinosteroids, a class of potent plant growth promoters. Microscale naphthoylation followed by circular dichroic (CD) spectroscopy measurement in acetonitrile unambiguously differentiate between the two possible vicinal syn-diol configurations, (22R,23R) and (22S,23S).
