An expedient route to 3-chlorothioxanthen-9-one 10,10-dioxide and derivation by palladium-catalyzed coupling: All Rights Reserved. Several substances are used for example 87199-18-6 and 14047-29-1 which are their cas registry numbers. An expedient route to 3-chlorothioxanthen-9-one 10,10-dioxide and derivation by palladium-catalyzed coupling. Lory, Pedro M. J.; Agarkov, Anton; Gilbertson, Scott R. (Program in Chemical Biology, Department of Pharmacology & Toxicology, University of Texas-Medical Branch, Galveston, TX 77555-0650, USA). Synlett, (18), 3045-3048 (English) 2006 Georg Thieme Verlag. CODEN: SYNLES. ISSN: 0936-5214. DOCUMENT TYPE: Journal CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Chem. was developed that allows for the synthesis of a series of novel tricyclic thioxanthen-9-one 10,10-dioxides. A regioselective synthesis of the novel core substrate 3-chlorothioxanthen-9-one 10,10-dioxide was achieved from thiophenol and 4-chloro-2-iodobenzoate in 85% yield over 3 steps without the need for chromatog. purifn. Subsequent microwave-assisted coupling methodol. afforded the desired novel 3-substituted tricyclic compds. in good to excellent yield. .
