METHOD OF PREPARING QUINOLINYL LACTAMS OR SALTS THEREOF |
摘要 |
<p>FIELD: chemical industry. SUBSTANCE: method of preparing new quinolinyl lactams of formula I: R<SB>1</SB> wherein B is structure of formula I: wherein B is structure of general formula II: C<SB>3</SB>-C<SB>6</SB> wherein Q is structure of formula III: R<SB>2</SB> wherein CR<SB>4</SB> is lower alkyl or saturated or unsaturated R<SB>4</SB> carbocycle optionally substituted by halogen; <EMI ID=0.296 HE=9 WI=21 TI=CHI> is hydrogen or amino group; A is nitrogen or <EMI ID=0.297 HE=66 WI=84 TI=CHI> wherein <EMI ID=0.298 HE=27 WI=48 TI=CHI> is halogen or hydrogen; P is piperazinyl unsubstituted or substituted by lower alkyl or group of formula IV: <EMI ID=0.299 HE=15 WI=30 TI=CHI> wherein Hal is fluorine, chlorine, bromine or iodine, or salts thereof. Said method comprises reacting lactam compound B-OH wherein B is as defined above, in which functional hydroxyl and carboxyl groups are optionally protected, with phosgene at temperature from -80 C to about 0 C to form intermediate product of formula V: <EMI ID=0.300 HE=9 WI=15 TI=CHI> wherein B is as defined above, reacting the resulting intermediate product with compound of general formula HQ wherein Q is as defined above in which functional carboxyl group is optionally protected, subsequently removing protective groups and isolating the desired product in free state or as salt. EFFECT: new compounds have valuable properties. 8 cl, 3 ex</p> |
