结果表明,在质子传递溶剂(如H 2 O. MeOH和EtOH)中,在H 2 SO 4存在下,辐照2-烯丙基化的苯胺(参见方案2-4、7和8)经历了新的光解反应特别地产生反式-2-羟基和反式-2-烷氧基-1-甲基茚满。中间体大概是在分子内[2 s + 2 s ]环加成反应中形成的三环[4.3.0.0 1,8 ] nona-2,4-二烯(参见方案7)。另一方面,N,N,N-三甲基-2-(1'-甲基烯丙基)苯胺盐18(方案6)和2-(3'-丁烯基)-N,N-二甲基苯胺(17)在MeOH或H 2 SO 4 / MeOH中辐射后,铵基还原生成(1-甲基烯丙基)苯(19)和1-甲基茚满(20)。
[Object]: To provide a compound having a novel structure effective against Hemophilus influenzae and erythromycin resistant bacteria (for example, resistant pneumococci and streptococci) as well as against conventional erythromycin sensitive bacteria.
[Solution]: A novel 10a-azalide compound represented by the formula (I), a pharmaceutically acceptable salt thereof or a solvate thereof, or an intermediate for the preparation of the same. The compound of the present invention has superior antibacterial activity against Hemophilus influenzae, erythromycin resistant pneumococci and the like, and therefore, the compound can be used as a therapeutic agent of infectious diseases.

or a pharmaceutically acceptable salt, N-oxide or tautomer thereof; wherein:
n is 1 or 2;
X is CH or N;
Y is selected from CH and C—F;
Z is selected from C—Rz and N;
R1 is selected from:
-(Alk1)t-Cyc1; wherein t is 0 or 1;
Optionally substituted C1-6 acyclic hydrocarbon groups
R2 is selected from hydrogen; halogen; and C1-3 hydrocarbon groups optionally substituted with one or more fluorine atoms;
R3 is hydrogen or a group L1-R7;
R4 is selected from hydrogen; methoxy; and optionally substituted C1-3 alkyl; and
R4a is selected from hydrogen and a C1-3 alkyl group;
wherein Rz, Alk1, Cyc1, L1 and R7 are defined herein;
provided that the compound is other than 6-benzyl-3-2-[(2-methylpyrimidin-4-yl)amino]pyridin-4-yl}-7,8-dihydro-1,6-naphthyridin-5(6H)-one and 3-2-[(2-methylpyrimidin-4-yl)amino]pyridin-4-yl}-7,8-dihydro-1,6-naphthyridin-5(6H)-one and salts and tautomers thereof.
The compounds are inhibitors of ERK1/2 kinases and will be useful in the treatment of ERK1/2-mediated conditions. The compounds are therefore useful in therapy, in particular in the treatment of cancer.
