Abstract
Description
55 Die Erfindung betrifft den in den Ansprüchen 1 und 2 definierten Gegenstand. 55 The invention relates to the object defined in claims 1 and 2.
Zur Verseifung der Verbindungen der Formel II verfährt man vorzugsweise in Gegenwart einer Base, z.B. in Gegenwart eines Alkalimetallhydroxyds oder -hydrids. To saponify the compounds of formula II, the procedure is preferably in the presence of a base, e.g. in the presence of an alkali metal hydroxide or hydride.
60 Falls in optisch aktiver Form, weisen die Verbindungen vorzugsweise folgende Konfiguration auf: 60 If in an optically active form, the connections preferably have the following configuration:
H T H T
65 CH2 C - 65 CH2 C -
I A I A
O O O O
cm i cm i
N N
Die Verbindungen sind vorzugsweise in optisch aktiver Form. The compounds are preferably in optically active form.
Die Verbindungen der Formel II erhält man dadurch, dass man in entsprechende Verbindungen der Formel III, The compounds of the formula II are obtained by converting the corresponding compounds of the formula III into
