    摘要: To develop a protecting group that facilitates separation and purification, after reaction, of a compound including a protected functional group, without solidifying or insolubilizing the compound.
    A xanthene compound of by General Formula (1)

    (wherein Y is -OR 17 (R 17 is a hydrogen atom or an active ester-protecting group), -NHR 18 (R 18 is a hydrogen atom, or a linear or branched C 1 -C 6 alkyl group or aralkyl group), an azide, a halogen atom, or a carbonyl group formed together with a methylene group;
    at least one of R 1 to R 8 is represented by Formula (2);

            -O-R 9 -X-A     (2)

    and a residue is a hydrogen atom, a halogen atom, a C 1 -C4 alkyl group, or a C 1 -C 4 alkoxy group,
    wherein R 9 is a linear or branched C 1 -C 16 alkylene group;
    X is O or CONR 19 (R 19 is a hydrogen atom or a C 1 -C 4 alkyl group); and
    A is represented by Formula (3) or the like

    (wherein R 10 , R 11 , and R 12 , the same or different, are a linear or branched C 1 -C 6 alkyl group or an aryl group optionally including a substituent;
    R 13 is a single bond or a linear or branched C 1 -C 3 alkylene group; and
    R 14 , R 15 , and R 16 are a linear or branched C 1 -C 3 alkylene group)).
