Muro, Tomio et al. published their research in Yakugaku Zasshi in 1982 | CAS: 7476-66-6

Methyl 2-chloro-2-phenylacetate (cas: 7476-66-6) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.SDS of cas: 7476-66-6

Studies of thiomorpholine derivatives. III. Reaction of 2-substituted-3-oxoperhydro-2H-1,4-thiazine-5-carboxylic acids and their methyl esters with sulfuryl chloride was written by Muro, Tomio. And the article was included in Yakugaku Zasshi in 1982.SDS of cas: 7476-66-6 This article mentions the following:

Each diastereomer was isolated from a mixture of (2R,5R)-I and (2S,5R)-I, which was derived from L-cysteine, by using SOCl2 and their stereostructure was clarified by NMR. When each diastereomer I was treated with equivalent SO2l2, (1S,4R)-II was obtained. The reaction of thiazinecarboxylates III (R = Et, Me2CH) with SO2Cl2 afforded alkylidene-thiazinecarboxylates IV (R1 = H, Me). The reaction of (5R)-III (R = Ph) with SO2Cl2 gave [PhCOCONHCH(CO2Me)CH2S]2 and (2R,5R,2′S,5′S)-V. In the experiment, the researchers used many compounds, for example, Methyl 2-chloro-2-phenylacetate (cas: 7476-66-6SDS of cas: 7476-66-6).
