Stereoisomers of steroidal 22-hydroxy-, 23-acetylenic, 23-olefinic and 23,24-isomeric epoxides were synthesized from C-22 aldehydes and their (13)C NMR spectra were analysed.A correlation regarding the combined effect of the 22-hydroxy and 23,24-substituents on the stereochemistry of the attached groups at C-22, -23 and -24 is derived.KEY WORDS: Brassinolide; Configurational assignment; 22-Hydroxy-23,24-epoxysteroids; (13)C NMR
