Single Route to Chiral s yn- and a nti-2-Amino-1,2-diphenylethanols via a New Stereodivergent Opening of trans-1,2-Diphenyloxirane

Oxiranyl ring opening of trans-stilbene oxide gave rise to anti- or syn-2-bromo-1,2-diphenylethanols, using either MgBr2·Et2O or MgBr2·Et2O, NaBr, and KBr with Amberlyst 15, respectively. Starting from optically pure (R,R)-trans-stilbene oxide, (1R,2R)- and (1R,2S)-2-amino-1,2-diphenylethanols were...

Zusammenfassung:Oxiranyl ring opening of trans-stilbene oxide gave rise to anti- or syn-2-bromo-1,2-diphenylethanols, using either MgBr2·Et2O or MgBr2·Et2O, NaBr, and KBr with Amberlyst 15, respectively. Starting from optically pure (R,R)-trans-stilbene oxide, (1R,2R)- and (1R,2S)-2-amino-1,2-diphenylethanols were obtained in high yield and ee.
