In the last decades the spectacular results of each
developmental stages of
computer-aided design, were considered as great magic of
computer use.
Professionals were shocked by the impressive building of
engineer works and
their more and more realistic appearance. It was hard to believe
and for many
people it still is that this technology becomes indispensable in
everyday
engineering work. By now, in front-rank product development, it
is impossible to
do a competitive designer work without applying the most up-to-
date design
technology. This all leads to the fact that an engineer student
of our days, in his
design practice, is definitely going to work with the
momentarily most up-to-date
technology, which will be out-of-date in a couple of years. |
A számĂtĂłgĂ©pek alkalmazásának nagy varázslatai közĂ© számĂtott az
elmĂşlt
Ă©vtizedekben a számĂtĂłgĂ©pen vĂ©gzett tervezĂ©s egy-egy fejlıdĂ©si
szakaszának
látványos eredménye. Szakembereket is meghökkentett a mérnöki
alkotások
látványos Ă©pĂtĂ©se Ă©s mind valĂłsághĹ‘bb megjelenĂtĂ©se. Nehezen
hitték, sıt sokan
ma is nehezen hiszik azt, hogy a mérnöki munka mindennapjaiban
is
nélkülözhetetlenné válik ez a technika. Mára az élvonalbeli
termékfejlesztésben a
mindenkori legjobb tervezési technika igénybevétele nélkül
képtelenség
versenyképes tervezımunkát végezni. Ennek következtében napjaink
mérnökhallgatója tervezıi gyakorlatában minden bizonnyal a ma
legkorszerĹ‘bbnek számĂtĂł, de nĂ©hány Ă©v alatt elavulĂł mĂłdszert
leváltó
technikával fog dolgozni.

The first synthesis of 3-deoxyoripavine and its utilization in the preparation of 10-deoxyaporphines and cyprodime
The synthesis of 3-deoxyoripavine (7) was realized as a novel
and promising intermediate towards the synthesis of the
important class of dopaminergic and/or serotonergic 10-
deoxyaporphines and the special pharmacological tool µ opioid
antagonist cyprodime. Generally, the preparation of these
valuable biologically active compounds was achieved in
remarkable yields
