Two different monomers, 1,6-anhydro-2-azido-mannose derivative (3) and 1,6-anhydro-2-(N, N-dibenzylamino)-mannose derivative (6), were synthesized and polymerized. Although 3 gave merely oligomers, 6 was promptly polymerized into high polymers of the number-average molecular weight (Mn) of 2.3 \u00d7 104 to 2.9 \u00d7 104 with 1,6-\u03b1 stereoregularity. The differences of polymerizability of 3 and 6 from those of the corresponding glucose homologs were discussed. It was found that an N-benzyl group is exceedingly suitable for protecting an amino group in the polymerization of anhydro sugars of a mannosamine type. The simultaneous removal of O- and N-benzyl groups of the resulting polymers was achieved by using sodium in liquid ammonia to produce the first 2-amino-glycan, poly-(1[RIGHTWARDS ARROW]6)-\u03b1-D-mannosamine, having high molecular weight through ring-opening polymerization of anhydro sugars.", "subitem_description_type": "Abstract"}]}, "item_3_full_name_183": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "44875", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "1000020333669 ", "nameIdentifierScheme": "NRID", "nameIdentifierURI": "http://rns.nii.ac.jp/d/nr/1000020333669 "}], "names": [{"name": "\u670d\u90e8, \u548c\u5e78"}]}, {"nameIdentifiers": [{"nameIdentifier": "44876", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "1000040166955 ", "nameIdentifierScheme": "NRID", "nameIdentifierURI": "http://rns.nii.ac.jp/d/nr/1000040166955 "}], "names": [{"name": "\u5409\u7530, \u5b5d"}]}]}, "item_3_publisher_212": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Wiley"}]}, "item_3_relation_191": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://doi.org/10.1002/pola.26262", "subitem_relation_type_select": "DOI"}}]}, "item_3_rights_192": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "c 2012 Wiley Periodicals, Inc."}, {"subitem_rights": "This is the peer reviewed version of the following article:J Polym Sci Part A: Polym Chem (2012) 50: 4524-4531, which has been published in final form at http://doi.org/10.1002/pola.26262.
