Safety of (S)-4-Isopropyl-5,5-diphenyloxazolidin-2-one, Chemical engineers work across a number of sectors, processes differ within each of these areas, but chemistry and chemical engineering roles are found throughout in the manufacturing process of chemical products. 184346-45-0, Name is (S)-4-Isopropyl-5,5-diphenyloxazolidin-2-one, molecular formula is C18H19NO2
(Equation Presented) The 3-methylthiomethyl-4-isopropyl-5,5-diphenyl-1,3-oxazolidin-2-one (I, prepared in three steps from Boc-valine ester) is lithiated and added to aldehydes, with protecting in situ trapping of the primary adducts, to give the N,S-acetal derivatives II of 2-hydroxy a dehydes in high yields and diastereoselectivities. Cleavage (with ready recovery of the oxazolidinone auxiliary) is possible, to afford, for instance, enantiopure 1,2-diols, selectively protected (OBn, OMOM, OTBS) in the 2-position.
