Computed Properties of C14H14O2《A mild access to chiral syn 1,2-diaryl glycols by stereoselective ring opening of ortho substituted trans 2,3-diaryl-oxiranes using Amberlyst 15 in H2O/THF system》 was published in 2015. The authors were Lupattelli, Paolo;Chiummiento, Lucia;Funicello, Maria;Tramutola, Francesco;Marmo, Antonella;Gliubizzi, Natascia;Tofani, Daniela, and the article was included in《Tetrahedron》. The author mentioned the following in the article:
Amberlyst 15 was an efficient and green catalyst for the reaction of 2,3-diaryloxiranes with H2O in organic co-solvent to prepare glycols in high yield. Ortho substituted trans 2,3-diaryloxiranes afforded the corresponding syn glycols stereo- and enantiospecifically. Stereoselectivity appeared related to the coordination ability of the substituents, irresp. of their electronic properties. Indeed o-OCH3 and o-OBn substituted syn glycols were obtained in high stereochem. ratios (6/1 and 10/1, resp.), and o-OTIPS and o-NO2 substituted ones were obtained as exclusive products, with the same ee of the parent epoxides.rel-(1R,2S)-1,2-Diphenylethane-1,2-diol (cas: 579-43-1) were involved in the experimental procedure.
rel-(1R,2S)-1,2-Diphenylethane-1,2-diol(cas: 579-43-1 Computed Properties of C14H14O2) has been used in the preparation of trans-methyl meso-hydrobenzoin phosphite.
