Intermediates useful for synthesizing dibenzorhodamine compounds having structure (1), including nitrogen- and aryl-substituted forms thereof, are disclosed, such intermediates having structure formula (I). In formula (I), R1 is H or -C(O)Y wherein Y is H, lower alkyl, lower alkene, lower alkyne, aromatic, phenyl, polycyclic aromatic, heterocycle, water-solubilizing group, or linking group, including substituted forms thereof. When R1 is H, the C-12-bonded nitrogen and the C-12 and C-13 carbons form a first ring structure having from 4 to 7 members, and/or the C-12-bonded nitrogen and the C-11 and C-12 carbons form a second ring structure having from 5 to 7 members.
本发明公开了用于合成具有结构(1)的二苯并罗丹明化合物的中间体,包括其氮代和芳基取代形式,此类中间体具有结构式(I)。在式 (I) 中,R1 是 H 或 -C(O)Y 其中 Y 是 H、低级烷基、低级烯基、低级炔基、芳香族、苯基、多环芳香族、杂环、水溶性基团或连接基团,包括其取代形式。当 R1 为 H 时,C-12 键氮与 C-12 和 C-13 碳形成具有 4 至 7 个成员的第一环结构,和/或 C-12 键氮与 C-11 和 C-12 碳形成具有 5 至 7 个成员的第二环结构。
