Chemistry is traditionally divided into organic and inorganic chemistry. SDS of cas: 4602-73-7, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 4602-73-7

The highly convergent stereocontrolled total synthesis of (-)-vincamajinine (7), (-)-11-methoxy-17-epivincamajine (9), and the oxygen-bridged (+)-dehydrovoachalotine (22) are described. Key steps in the synthesis of 7 and 9 involved the stereospecific enolate-driven palladium-catalyzed cross-coupling reaction, a Tollens reaction, an acid-assisted intramolecular cyclization to form the C(7)-C(17) quaternary center, and two stereospecific reductions. The efficiency of this strategy is illustrated by the completion of the synthesis of 7 and 9 in 16 [from D-(+)-tryptophan methyl ester 17] and 17 (from the Schoellkopf chiral auxiliary 27) reaction vessels, respectively. This constitutes the first total synthesis of these indole alkaloids and provides the first regiospecific route to 11-methoxy-substituted ajmaline/vincamajine- related alkaloids. The synthesis of 22 required a novel DDQ-mediated cyclization to furnish the C(6)-O(17) bond, executed in stereospecific fashion. Completion of these syntheses illustrates a concise and versatile strategy for the synthesis of vincamajine-related alkaloids, which has also been employed to prepare the related compounds quebrachidine diol (53), vincamajine diol (56), and vincarinol (59).

(R)-(+)-8,9-Dimethoxy-6,10b-dihydro-5H-thiazolo[2,3-a]isoquinolin-3-one 1 has been synthesized from 6,7-dimethoxy-3,4-dihydroisoquinoline and menthyl thioglycolate. Compound 1 was obtained in the enantiomerically pure form (mp 150-153C, [alpha]D +436) by a single crystallization of the crude reaction product (68% e.e.) from 96% ethanol. The absolute 10bR configuration was established by X-ray diffraction. Oxone oxidation of 1 resulted in a configurationally unstable dextrorotatory syn-sulfoxide 2 (mp 173-175C, [alpha]D +62.8).

The synthesis and optimization of the anti-Helicobacter pylori activity of a novel series of benzyloxyisoquinoline derivatives that was discovered by a random screening process, are described. In the in vitro assay, compound 10c containing a 3-acetamido-2,6-dichlorobenzyl substituent was found to have extremely potent activity against H. pylori and no activity against other common bacteria. The anti-H. pylori activity of 10c was superior to that of amoxicillin (AMPC) (1) and clarithromycin (CAM) (2). However, 10c did not show in vivo efficacy in a mouse infection model; a feature attributed to the lack of strong bactericidal activity at short contact times. (C) 1999 Elsevier Science Ltd.
