摘要

Aminophenyl pyrrolidine derivatives (I) are new. Aminophenyl pyrrolidine derivatives of formula (I) and their acid addition salts are new: [Image] R1halo, Z, or 1-8C aliphatic or alicyclic hydrocarbyl optionally containing O, N, Si, S or SO2 and optionally substituted with OH, OA, NH2, NHA or NAA; n : 0-4; Z : an onium group; A : 1-4C alkyl; R2Z, COOH, COOA, CONH2, CONHA or CONAA; 1-6C alkyl; optionally unsaturated 1-6C alkyl substituted with OH, OA, NH2, NHA, NAA, SH, SO2A or halo; optionally unsaturated 1-6C alkyl substituted with COOH, COA, COOA, CONH2, CONHA or CONAA; or 4- to 7-membered heterocyclyl containing N, O and/or S; R3Z, H, OH, OA, NH2, NHA, NAA, SH, COOH, COOA, CONH2, CONHA, CONAA or SO2A; 1-6C alkyl; optionally unsaturated 1-6C alkyl substituted with OH, OA, NH2, NHA, NAA, SH, SO2A or halo; optionally unsaturated 1-6C alkyl substituted with COOH, COA', COOA', CONH2, CONHA', CONA'A' or 4- to 7-membered heterocyclyl containing N, O and/or S; or 4- to 7-membered heterocyclyl containing N, O and/or S; A' : 1-6C alkyl; provided that at least one of R2 and R3 is Z. Independent claims are also included for: (1) nitrophenyl pyrrolidine derivatives of formula (I'); (2) oxidation dye composition comprising at least one compound (I) as developer; (3) oxidation dyeing of keratinic fibers by applying a composition as above in the presence of an oxidizing agent; (4) kit comprising a composition as above in one compartment and an oxidizing agent in another compartment.
