Zur Epimerisierung des (±)‐erythro‐ und des (1S.2R)‐1‐p‐Nitrophenyl‐2‐amino‐propandiols‐(1.3)

Abstract: Die Epimerisierung a m C-1 von (~)-eiythro-l-p-Nitrophenyl-2-amino-propandiol-(1.3) und dessen (1 S.2 R)-Modifikation wird durch Oxydation der Diacetylverbindung I1 zum Keton 111, selektives Entacetylieren am 0 -3 und stereospezifische Reduktion des Acetaminoketons IV mittels Calciumborhydrids zu (*)-threo-V bzw. zu (1 R.ZR)-V rnit einer Gesamtausbeute von 56% erzielt.Einige Methoden zur Herstellung des (&)-threo-1 -p-Nitrophenyl-2-amino-propandiols-( 1.3), des Alkamins von Chloramphenicol, beruhen auf der Epi… Show more

“…Reaction of the Lewis acid with permanganate would cause the metal center (manganese) to become more positive, as in Scheme 1. The Lewis acid acts in much the same way as a Bronsted acid does in the reactions of permanganate in protic media 15 .…”
