PRIORITY: DE 2002-10235267 1 Aug 2002. DOCUMENT TYPE: Patent CA Section: 39 (Synthetic Elastomers and Natural Rubber) Section cross-reference(s): 17 Shaped bodies comprise addn.-crosslinked silicone elastomers crosslinked in the presence of at least one rhodium or iridium catalyst or mixts. of both catalyst types. The shaped bodies may be made transparent and colorless and are well suited for use as food and baking molds in the food industry. The catalyzed addn.-crosslinkable components display excellent pot life as well as good high temp. cure.Except for chemicals metioned above, 14874-82-9 and 73482-96-9 are also used. .

Synthesis of methylphenidate analogues and their binding affinities at dopamine and serotonin transport sites

Synthesis of methylphenidate analogues and their binding affinities at dopamine and serotonin transport sites. Davies, Huw M.Several substances are used for example 73482-96-9 which is its cas registry number. L.Several substances like 73482-96-9 may be metioned in this study.; Hopper, Darrin W.; Hansen, Tore; Liu, Quixu; Childers, Steven R.

CODEN: BMCLE8. ISSN: 0960-894X. DOCUMENT TYPE: Journal CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Section cross-reference(s): 1 The rhodium(II)-catalyzed intermol. C-H insertion of Me aryldiazoacetates with either N-Boc-piperidine or N-Boc-pyrrolidine followed by deprotection with trifluoroacetic acid is a very direct method for the synthesis of methylphenidate analogs, e.g. I. By using either dirhodium tetraacetate or dirhodium tetraprolinate derivs. as catalyst, either the racemic or enantioenriched methylphenidate analogs can be prepd. The binding affinities of the methylphenidate analogs to both the dopamine and the serotonin transporters are described. The most notable compds. are the erythro-(2-naphthyl) analogs, e.g. I×HCl, which display high binding affinity and selectivity for the serotonin transporter. ..
