Practical Synthesis and Elaboration of Methyl 7-Chloroindole-4-carboxylate
摘要:
A synthesis of a previously unknown indole derivative is presented. The route reported herein allows for the preparation of multihundred gram quantities of material without any chromatographic purification. Conditions are presented for the Pd-catalyzed elaboration of one of the "diversity generating elements" of this important pharmacophore.

The synthesis of diverse substituted indole structures on solidsupports is described. The immobilization of nitrobenzoic acid onto Merrifield resin and the subsequent treatment with alkenyl Grignard reagents delivered indole carboxylates bound to solidsupports. In contrast to results in the liquid phase, ortho,ortho-unsubstituted nitroarenes also delivered indole moieties in good yields. Subsequent
The present invention provides compounds of formula M-L-M' (where M and M' are each independently a monomeric moiety of Formula (I) and L is a linker). The dimeric compounds have been found to be effective in promoting apoptosis in rapidly dividing cells. (I)
[reaction: see text] Bartoli indolesynthesis has been performed for the first time on solidsupports. Starting from Merrifield resin, immobilization of five nitro benzoic acids was performed. Addition of four different alkenyl Grignard reagents and basic cleavage leads to substituted methyl indole carboxylates in excellent purities. Features of this reaction are the stability of halide groups, ester
The present invention provides compounds of formula M-L-M′ (where M and M′ are each independently a monomeric moiety of Formula (I) and L is a linker). The dimeric compounds have been found to be effective in promoting apoptosis in rapidly dividing cells. (I)
The present invention provides, compounds, methods and compositions of biologically important indoles. In addition, the present invention provides synthesis methods for substituting leaving groups at positions 4 and 7 of the indole ring as diversity generating elements.
