High chemoselectivity for the C5C6epoxidation of cholesterol derivatives without protecting other oxidizable functional groups was achieved on a newly designed molecularly imprinted Ru–porphyrin catalyst using a SiO2-support.
Two new brassinosteroids analogues containing a 3,6-dione with a 5a-hydroxyl group and also one epoxy ring in the side chain have been synthesised from stigmasterol. Their activity as plant growth promoter has been tested using Radish ( Raphanus sativus) tests.
