| Summary: | Disclosed are novel compounds represented by Structural Formula II, IX or XXVIII:
1
R
1
, R
21
and R
22
are independently an aliphatic group, a substituted aliphatic group, an aromatic group or a substituted aromatic group.
R
2
is -NR
4
R
5
or -N
+
≡C
−
.
Alternatively, R
1
and R
2
, taken together with the methine group to which they are bonded, are a moiety represented by the following structural formula:
2
R
3
is -NH
2
, -OH, -OC(O)H or -OR
9
.
R
5
, R
6
and R
7
are independently -H or an amine protecting group.
R
8
is -H, -OH or -OR
8
.
R
9
is an alcohol protecting group.
Also disclosed are methods of preparing these compounds. |
