Synthesis of the core alpha,alpha-trehalose 2-sulfate.\nalpha,alpha-Trehalose 2-sulfate, the core carbohydrate of sulfatides of Mycobacterium tuberculosis, and the 3-sulfate isomer were synthesized by sulfation of 4,6:4',6'-di-O-benzylidene-alpha,alpha-trehalose with pyridine-sulfur trioxide complex to give the 2- and 3-sulfates, which were separated by column chromatography. The ammonium 2-sulfate salt wa was identical with the natural product obtained from the principal sulfatide (SL-I) of M. tuberculosis.","tracks":[{"project":"sentences","denotations":[{"id":"TextSentencer_T1","span":{"begin":0,"end":41},"obj":"Sentence"},{"id":"TextSentencer_T2","span":{"begin":42,"end":96},"obj":"Sentence"},{"id":"TextSentencer_T3","span":{"begin":97,"end":419},"obj":"Sentence"},{"id":"TextSentencer_T4","span":{"begin":420,"end":554},"obj":"Sentence"},{"id":"T1","span":{"begin":0,"end":41},"obj":"Sentence"},{"id":"T2","span":{"begin":42,"end":96},"obj":"Sentence"},{"id":"T3","span":{"begin":97,"end":419},"obj":"Sentence"},{"id":"T4","span":{"begin":420,"end":554},"obj":"Sentence"}],"namespaces":[{"prefix":"_base","uri":"http://pubannotation.org/ontology/tao.owl#"}],"attributes":[{"subj":"TextSentencer_T1","pred":"source","obj":"sentences"},{"subj":"TextSentencer_T2","pred":"source","obj":"sentences"},{"subj":"TextSentencer_T3","pred":"source","obj":"sentences"},{"subj":"TextSentencer_T4","pred":"source","obj":"sentences"},{"subj":"T1","pred":"source","obj":"sentences"},{"subj":"T2","pred":"source","obj":"sentences"},{"subj":"T3","pred":"source","obj":"sentences"},{"subj":"T4","pred":"source","obj":"sentences"}]},{"project":"NCBITAXON","denotations":[{"id":"T1","span":{"begin":14,"end":40},"obj":"OrganismTaxon"},{"id":"T2","span":{"begin":169,"end":195},"obj":"OrganismTaxon"}],"attributes":[{"id":"A1","pred":"db_id","subj":"T1","obj":"1773"},{"id":"A2","pred":"db_id","subj":"T2","obj":"1773"},{"subj":"T1","pred":"source","obj":"NCBITAXON"},{"subj":"T2","pred":"source","obj":"NCBITAXON"}]},{"project":"mondo_disease","denotations":[{"id":"T1","span":{"begin":28,"end":40},"obj":"Disease"},{"id":"T2","span":{"begin":183,"end":195},"obj":"Disease"},{"id":"T3","span":{"begin":541,"end":553},"obj":"Disease"}],"attributes":[{"id":"A1","pred":"mondo_id","subj":"T1","obj":"http://purl.obolibrary.org/obo/MONDO_0018076"},{"id":"A2","pred":"mondo_id","subj":"T2","obj":"http://purl.obolibrary.org/obo/MONDO_0018076"},{"id":"A3","pred":"mondo_id","subj":"T3","obj":"http://purl.obolibrary.org/obo/MONDO_0018076"},{"subj":"T1","pred":"source","obj":"mondo_disease"},{"subj":"T2","pred":"source","obj":"mondo_disease"},{"subj":"T3","pred":"source","obj":"mondo_disease"}]},{"project":"GlyCosmos6-Glycan-Motif-Structure","denotations":[{"id":"T1","span":{"begin":0,"end":10},"obj":"https://glytoucan.org/Structures/Glycans/G40843KY"},{"id":"T2","span":{"begin":0,"end":10},"obj":"https://glytoucan.org/Structures/Glycans/G72548RZ"},{"id":"T3","span":{"begin":0,"end":10},"obj":"https://glytoucan.org/Structures/Glycans/G95090DW"},{"id":"T4","span":{"begin":155,"end":165},"obj":"https://glytoucan.org/Structures/Glycans/G40843KY"},{"id":"T5","span":{"begin":155,"end":165},"obj":"https://glytoucan.org/Structures/Glycans/G72548RZ"},{"id":"T6","span":{"begin":155,"end":165},"obj":"https://glytoucan.org/Structures/Glycans/G95090DW"},{"id":"T7","span":{"begin":518,"end":527},"obj":"https://glytoucan.org/Structures/Glycans/G40843KY"},{"id":"T8","span":{"begin":518,"end":527},"obj":"https://glytoucan.org/Structures/Glycans/G72548RZ"},{"id":"T9","span":{"begin":518,"end":527},"obj":"https://glytoucan.org/Structures/Glycans/G95090DW"}],"attributes":[{"subj":"T1","pred":"source","obj":"GlyCosmos6-Glycan-Motif-Structure"},{"subj":"T2","pred":"source","obj":"GlyCosmos6-Glycan-Motif-Structure"},{"subj":"T3","pred":"source","obj":"GlyCosmos6-Glycan-Motif-Structure"},{"subj":"T4","pred":"source","obj":"GlyCosmos6-Glycan-Motif-Structure"},{"subj":"T5","pred":"source","obj":"GlyCosmos6-Glycan-Motif-Structure"},{"subj":"T6","pred":"source","obj":"GlyCosmos6-Glycan-Motif-Structure"},{"subj":"T7","pred":"source","obj":"GlyCosmos6-Glycan-Motif-Structure"},{"subj":"T8","pred":"source","obj":"GlyCosmos6-Glycan-Motif-Structure"},{"subj":"T9","pred":"source","obj":"GlyCosmos6-Glycan-Motif-Structure"}]},{"project":"GlyCosmos6-Glycan-Motif-Image","denotations":[{"id":"T1","span":{"begin":0,"end":10},"obj":"Glycan_Motif"},{"id":"T4","span":{"begin":155,"end":165},"obj":"Glycan_Motif"},{"id":"T7","span":{"begin":518,"end":527},"obj":"Glycan_Motif"}],"attributes":[{"id":"A1","pred":"image","subj":"T1","obj":"https://api.glycosmos.org/wurcs2image/0.10.0/png/binary/G95090DW"},{"id":"A2","pred":"image","subj":"T1","obj":"https://api.glycosmos.org/wurcs2image/0.10.0/png/binary/G72548RZ"},{"id":"A3","pred":"image","subj":"T1","obj":"https://api.glycosmos.org/wurcs2image/0.10.0/png/binary/G40843KY"},{"id":"A4","pred":"image","subj":"T4","obj":"https://api.glycosmos.org/wurcs2image/0.10.0/png/binary/G95090DW"},{"id":"A5","pred":"image","subj":"T4","obj":"https://api.glycosmos.org/wurcs2image/0.10.0/png/binary/G72548RZ"},{"id":"A6","pred":"image","subj":"T4","obj":"https://api.glycosmos.org/wurcs2image/0.10.0/png/binary/G40843KY"},{"id":"A7","pred":"image","subj":"T7","obj":"https://api.glycosmos.org/wurcs2image/0.10.0/png/binary/G95090DW"},{"id":"A8","pred":"image","subj":"T7","obj":"https://api.glycosmos.org/wurcs2image/0.10.0/png/binary/G72548RZ"},{"id":"A9","pred":"image","s
