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 × 104 to 2.9 × 104 with 1,6-α 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)-α-D-mannosamine, having high molecular weight through ring-opening polymerization of anhydro sugars.","subitem_description_type":"Abstract"}]},"item_3_full_name_183":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"44875","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"20333669","nameIdentifierScheme":"KAKEN","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000020333669 "}],"names":[{"name":"服部, 和幸","nameLang":"ja"}]},{"nameIdentifiers":[{"nameIdentifier":"44876","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"40166955","nameIdentifierScheme":"KAKEN","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000040166955 "}],"names":[{"name":"吉田, 孝","nameLang":"ja"}]}]},"item_3_publisher_212":{"attribute_name":"出版者","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":"権利","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.
