Soluble polymer supported 2-imidazolidinone chiral auxiliary and method for manufacturing the same
-
Paragraph 0068, (2017/01/02)
The present invention relates to a chiral auxiliary agent and a manufacturing method thereof and, more specifically, to a 2-imidazolidinone chiral auxiliary agent supported onto a polymer soluble in an organic solvent and a manufacturing method thereof. The chiral auxiliary agent in the present invention shows effects of being easy to separate reaction products and the chiral auxiliary agent after a termination of a reaction while fulfilling an economic efficacy of chiral auxiliary molecules by being supported onto the polymer soluble in the organic solvent.COPYRIGHT KIPO 2015

A new practical method for the synthesis of a non-cross-linked polystyrene supported 2-phenylimino-2-oxazolidine chiral auxiliary is reported. This method started from the same material as in a previous synthesis, N-Boc-L-tyrosine ethyl ester, but the overall yield was 42.5%, which was higher than the copolymerisation method.
