Abstract
The structure of the chlorohydrins I (R = Me, R1 = R2 = R3 = H; R = R2 = H, R1 = R3 = Me; R = R2 = Me, R1 = R3 = H), isolated as a 1:2:1 mixt. from the HCl hydrolyzate of a E. sepositus saponin mixt., were detd. from spectral data. I arose from the corresponding 22,23-epoxides during HCl hydrolysis of the saponins, since the corresponding bromohydrins were formed when the hydrolysis was performed using HBr.File in questo prodotto:
