Title: Preparation and synthetic application of partially protected brassinosteroids. Author: Khripach VA, Zhabinskii VN, Zhiburtovich YY, Ivanova GV, Konstantinova OV, Tsavlovskii DV, Lorenz S, Schneider B. Journal: Steroids; 2010 Jan; 75(1):27-33. PubMed ID: 19786042. Abstract: Preparation of partially protected brassinosteroids is achieved through the reaction of the source material (24-epicastasterone and 24-epibrassinolide) with diol-specific reagents (2,2-dimethoxypropane and methylboronic acid). The obtained products were shown to be useful synthetic intermediates for further preparation of minor representatives of this class of natural phytohormones (such as 3,24-diepicastasterone and 3-dehydro-24-epibrassinolide).[Abstract] [Full Text] [Related] [New Search]
