N-Chlorination-induced, oxidative ring contraction of 1,4-dimethoxyphthalazines

A rarely explored oxidative ring contraction of electron-rich 1,2-diazine is described. Upon treatment with an electrophilic chlorinating reagent (TCICA), 1,4-dimethoxyphthalazines undergo an N-chlorination-induced ring contraction that is accompanied by the loss of one nitrogen atom. The scope of this unusual reactivity was examined with a range of 1,4-dimethoxyphthalazine derivatives. In addition, a mechanism proceeding via a bicyclic species was proposed on the basis of an isolated reaction intermediate and DFT calculations.

An elementary termolecular reaction involves the simultaneous collision of three atoms, molecules, or ions.1,4-Dichloro-5-fluorophthalazine, cas is 23928-47-4,the phthalazine compound. 23928-47-4. Here is a downstream synthesis route of the compound 23928-47-4

A solution of l,4-dichloro-5-fluorophthalazine (79.5 mg, 0.44 mmol) and N- methyl-p-anisidine (78.0 mg, 0.57 mmol) in /-PrOH (3 mL) was heated to reflux for 1.5 h. The reaction mixture was cooled to rt and then concentrated onto a mixture of SiO2 and Na2CO3. The reaction mixture was purified by two gradient MPLC columns (SiO2, 0 to 100 %, EtOAc/hexanes, 30 min; then SiO2, 0 to 30 %, EtOAc/hexanes, 30 min.) to EPO provide 14.5 mg (15 %) of the title compounds as a 2:1 mixture. Major Isomer: 1H NMR (DMSO-J6) delta 7.98 – 8.04 (m, 1 H), 7.77 (td, 1 H), 7.24 (ddd, 1 H), 6.85 – 6.91 (m, 2 H), 6.73 – 6.79 (m, 2 H), 3.76 (s, 3 H), 3.59 (s, 3 H). MS (ES) 318 (M + H). Minor Isomer: 1H NMR (DMSO-J6) delta 7.44 (td, 0.5 H), ,7.32 – 7.44 (m, 1 H), 6.97 – 7.04 (m, 1 H), 6.80 – 6.87 (m, 1 H), 3.79 (s, 1.5 H), 3.58 (s, 1.5 H). MS (ES) 318 (M + H).
