Embodiment 1
[0097] The chemical synthesis of embodiment 1 compound 5a-5d
[0098] use this article figure 1 Scheme 1 is shown for the synthesis of compounds 5a-5d.
[0099] Reaction conditions: (a) NBS, hv, CH 3 CN; (b)NaN 3 , EtOH, reflux; (d) C 9 h 19 SO 2 Cl or C 5 h 11 SO 2 Cl, pyridine, CH 2 Cl 2 , 0°C to room temperature; (e) K + o - t-Bu, ether, water, 0°C to room temperature.
[0100] A first series of compounds were obtained from various substituted methyl toluates. The meta and / or para amines were prepared according to literature protocols. (Okada, Y. et al., Bromination by means of Sodium monobromoisocyanurate (SMBI) (bromination with sodium monobromoisocyanurate (SMBI)). Org. Biomolec. Chem. 2003, 1, 2506-2511). Using NBS in CH 3 After bromination of the methyl radical in CN, by reacting with NaN 3 / EtOH was refluxed to displace the bromine. Under Staudinger conditions, the azide was reduced to the free amine 3, which was then coupled with 1-pentanesulfo...
Embodiment 2
[0112] The synthesis of embodiment 2 compound 5e and 5f
[0113] use this article figure 2 Scheme 2 is shown for the synthesis of compounds 5e-5f.
[0114] Reaction conditions: (a) NH 3 , MeOH, reflux; (b) NaH, RSO 2 Cl, DMF, 0°C to room temperature; (c) NaOH, THF / water, 0°C to room temperature.
[0115] Ortho-substituted carboxylates require a different approach than meta- and para-compounds. Formation of indolinone 6 in the reaction between o-bromide and ammonia / MeOH (Kovtunenko, V.A. et al.; Condensation of o-(bromomethyl)benzoic acid with amines (o-(bromomethyl)benzoic acid and amine condensation), Ukrainskii Khimicheskii Zhurnal 1983, 49, 1099-1103), the indolinone 6 was coupled with alkanesulfonyl chloride and NaH in DMF to obtain The γ-lactam bond was readily cleaved by NaOH in THF / water to prepare carboxylic acids 5e and 5f.
[0116] General procedure for 7a-b. 1.5 mmol 6 was added to DMF (8 mL), and the solution was cooled to 0°C. NaH (1.65 mmol) was added f...
Embodiment 3
[0122] The synthesis of embodiment 3 compound 13a-13f
[0123] use this article image 3 Shown scheme 3 carries out the synthesis of compound 13a-13f
[0124] Reaction conditions: (a) NBS, hv, CH 3 CN; (b)P(OEt) 3 , reflux; (c) H 2 SO 4 , EtOH, reflux; (d) C 9 h 19 SO 2 Cl or C 5 h 11 SO 2 Cl, pyridine, CH 3 CN, 0°C to room temperature; (e) TMSBr, CH 2 Cl 2 , room temperature.
[0125] The synthesis of alkyl phosphonates 13a-f begins with protection of the starting toluidine as di-acylated aniline 8 (Brown, J.J.; Brown, R.K. Preparation of o-and p-acetamidobenzaldehydes (Preparation of o-acetaminobenzaldehyde and p-acetaminobenzaldehyde), Can. J. Chem. 1955, 33, 1819-1823). Use NBS / CH 3 Radical bromination of CN afforded benzyl bromide 9, which was converted to phosphonate 10 by Arbuzov reaction with triethylphosphite. Deprotection to aniline by exposure to refluxing acidic EtOH solution. After coupling of amine with alkanesulfonyl chloride to generate sul...
