This invention provides processes for the preparation of a compound of Formula I:
Y—C(═O)—C(R
1
)(R
2
)—CH
2
—S(O)
n
R
3
wherein:
Y is hydroxy or XONX, where each X is independently hydrogen, lower alkyl or lower acyl;
R
1
is hydrogen or lower alkyl;
R
2
is hydrogen, lower alkyl, aryl, aralkyl, cycloalkyl, cycloalkylalkyl, or R
1
and R
2
together with the carbon atom to which they are attached form a cycloalkyl or heterocyclo group;
R
3
is aryl; and
n is 0, 1 or 2.
The invention also provides novel aryl haloalkyl sulfide intermediates useful for the preparation of compounds of Formula I and novel methods of preparing aryl alkyl sulfides.
本发明提供了制备化合物I的过程:Y-C(═O)-C(R1)(R2)-
CH2-S(O)nR3,其中:Y为羟基或XONX,其中每个X独立地为氢、低烷基或低酰基;R1为氢或低烷基;R2为氢、低烷基、芳基、芳基烷基、环烷基、环烷基烷基,或R1和R2与它们所连接的碳原子一起形成环烷基或杂环烷基;R3为芳基;n为0、1或2。该发明还提供了新的芳基卤代烷基
硫醚中间体,用于制备化合物I,以及制备芳基烷基
硫醚的新方法。
