| titleOfInvention | Process for the preparation of phenolic compounds |
| abstract | The present invention relates to a process for the preparation of a compound of formula (I) wherein Rb is hydrogen, -NR6R7, hydroxy, -ORa, alkyl, aryl, arylalkyl, arylalkenyl, cycloalkyl, cycloalkylalkyl. , heteroaryl, heteroarylalkyl, heteroarylalkenyl, heterocyclyl, heterocyclylalkyl, and heterocyclylalkenyl, each of which is optionally substituted or the two Rb substituents are bonded to each other to form a ring which is optionally on carbon in addition to the groups 1-3 selected from the group consisting of NRa, oxy, thio, sulfinyl and sulfonyl, R1 is hydrogen, halogen, nitro, cyano, alkyl, haloalkyl, alkenyl, alkynyl, alkoxy, , haloalkoxy, azido, -S (O) t R4, - (CR8R8) qS (O) t R4, hydroxy, hydroxyalkyl, aryl, arylalkyl, arylalkenyl, aryl oxy, arylalkoxy), heteroaryl, heteroarylalkyl, heteroarylalkenyl, heteroarylalkoxy, heterocyclyl, heterocyclyl -alkyl), heterocyclyl-alkoxy, heterocyclyl-alkenyl, -NR 4 C (O) NR 4 R 5, -NR 4 C (S) NR q R 5, - (CR 8 R 8) q R 4 R 5, - (CR 8 R 8) q (O) NR 4 R 5, - (alkenyl) -C (O) NR 4 R 5 - (CR 8 R 8) q C (O) -NR 4 R 10, -S (O) 3 R 8 - (CR 8 R 8) q C (O) R 11 - (alkenyl) -C (O) R 11 - (alkenyl) - C (O) OR11, - (CR8R8) qC (O) OR11, - (CR8R8) qOC (O) R11, - (CR8R8) qNR4C (O) R11, - (CR8R8) qC (NR4) NR4R5, - (CR8R8) - -NR 4 C (NR 5) R 11, - (CR 8 R 8) NHS (O) 2 R 13, (CR 8 R 8) q S (O) 2 NR 4 R 5 or a group R 1 taken together with -O- (CH 2) s O-, or one or six-membered, to form a saturated or unsaturated cyclic group wherein alkyl, aryl, aralkyl, heteroaryl and heterocyclyl are optionally substituted; R4 and R5 are hydrogen, optionally substituted alkyl, aryl, aryl, alkyl, heteroaryl, heteroaryl, alkyl, heterocyclyl, heterocyclyl, or R4 and R5 taken together with the nitrogen atom to form a 5-7 member, optionally a \ t an additional heteroatom-containing cyclic group selected from the group consisting of azoxy, nitrogen and sulfur; R8 and R9 are hydrogen or alkyl; R10 - (alkyl) -C (O) 2R8; R11 is hydrogen, optionally substituted alkyl, aryl, arylalkyl, heteroaryl, heteroarylalkyl, heterocyclyl or heterocyclylalkyl; R13alkyl, aryl, arylalkyl, heteroaryl, heteroarylalkyl, heterocyclyl or heterocyclylalkyl; m is 0, 1, 2, 3 or 4; m 'and t are 0, 1 or 2; q is 0, 1, 2, 3, 4, 5, 6, 7,8, 9 or 10; and s is 1, 2 or 3. The process of the present invention may provide a sulfonamide compound in the phenolic ortho position while maintaining the phenol acidity. |
