The present invention relates to compounds of formula I:
1
wherein one of R
1
and R
4
is selected from the group consisting of H, and optionally substituted C
1-6
alkyl, C
3-7
cycloalkyl, C
3-7
cycloalkyl-C
1-4
alkyl, and phenyl-C
1-4
alkyl; and the other of R
1
and R
4
is an optionally substituted C
9-14
aryl group; R
2
and R
3
are either:
(i) independently selected from H, R, R′, SO
2
R, C(═O)R, (CH
2
)
n
NR
5
R
6
, where n is from 1 to 4 and R
5
and R
6
are independently selected from H and R, where R is optionally substituted C
1-4
alkyl, and R′ is optionally substituted phenyl-C
1-4
alkyl, or
(ii) together with the nitrogen atom to which they are attached, form an optionally substituted C
5-7
heterocyclic group; and their use as pharmaceuticals, in particular for treating conditions alleviated by the antagonism of a 5-HT
2B
receptor.

Compounds of formulae: (I), (II), (IIIa), (IIIb), (IVa) and (IVb): or a pharmaceutically acceptable salt thereof, for use as pharmaceuticals, in particular for the treatment of a condition alleviated by antagonism of a 5-HT2B receptor.
2-(methylthio)-4H-chromen-4-ones by intramolecular cyclization of easily accessible 1-(2-benzyloxy-aryl)-3,3-bis-methylsulfanyl-propenones. The synthesized chromen-4-ones turn out to be a key precursor for various kinds of chemical reactions. Mechanistically, we observed that iodine-mediated intramolecular cyclization of ketene dithioacetal proceeded through a radical pathway. 3-Halo-2-(methylthio)-4H-chromen-4-ones
开发了一种有效的碘介导方法,用于通过容易获得的 1-(2-苄氧基-芳基)-3,3-双-甲基硫烷基的分子内环化合成功能化的 2-(甲硫基)-4 H-色烯-4-酮-丙烯酮。合成的 chromen-4-ones 是各种化学反应的关键前体。从机制上讲,我们观察到碘介导的二硫代乙缩醛分子内环化是通过自由基途径进行的。3-Halo-2-(methylthio)-4 H -chromen-4-ones 是通过各种两锅或一锅卤化方法实现的。
