538-58-9, Name is 1,5-Diphenylpenta-1,4-dien-3-one, belongs to chiral-oxygen-ligands compound, is a common compound. Formula: C17H14OIn an article, once mentioned the new application about 538-58-9.
A simple and highly diasteroselective approach for the vicinal dichlorination of functional olefins
Organocatalytic stereospecific vicinal dicholorination of a wide variety of functionalized olefins such as ketoesters, esters, ketones, carvone, cholesterol and ethyl sorbate (27 examples) was achieved using inexpensive sulfuryl chloride as well as a simple phosphine catalyst under mild reaction conditions. The products were obtained with good to excellent yields and diastereoselectivities (up to 96% yield and >25 : 1 dr).
