Description

Method for preparing carbonyl alpha-substituted nitrogen compounds
The preparation method technical field of carbonyl "-substitution nitrogen-containing compound
Novel prepare carbonyl the present invention relates to a kind of " method of-substitution nitrogen-containing compound; this method includes; in the presence of a lewis acid; there is solvent or in the absence of solvent in the case of, make -1 generation ketone or-| the heterocyclic compound for aldehyde and primary amine, secondary amine or containing nitrogen-atoms reacts.Background technology
At present, usually using for ketone or | the heterocyclic compound for aldehyde and primary amine, secondary amine or containing nitrogen-atoms reacts, and prepares carbonyl, and "-substitution nitrogen-containing compound, its preparation method mainly has direct method and epoxy intermediate method.
Wherein direct method is-halogenated ketone or " -1 generation aldehyde and primary amine, secondary amine or the heterocyclic compound containing nitrogen-atoms directly react generation carbonyl《- substitution nitrogen-containing compound.Both with the halogen on 2-position substitution reaction can occur for heterocyclic compound of this method due to primary amine, secondary amine or containing nitrogen-atoms, it can also be reacted with the carbonyl carbon on 1-position, and temperature is higher, with the easier progress of carbonyl carbon reaction on 1- positions, i.e., accessory substance is more.
Such as Japan Patent JP 10114736 is reported by the chloro- 2-methyl isophthalic acids of 2--(4-methyl mercapto phenyl)- 1- acetone directly with morpholine react, under 130 °C flow back 10 hours, obtain 2- methyl isophthalic acids-(4-methyl mercapto phenyl)- 2-morpholine-1- acetone, reaction yield is 87 .9%.Its reaction sees below formula:
Figure IMGF000002_0001
Epoxy intermediate method is more general method, first-halogenated ketone or "-halogenated aldehyde elder generation With sodium methoxide reaction generation oxirane compound intermediate, the intermediate again with primary amine, secondary amine or the heterocyclic compound containing nitrogen-atoms reaction generation carbonyl-substitution nitrogen-containing compound.This method easily hydrolyzes generation hydroxy compounds due to -1 generation ketone or ^ -1 generations aldehyde, epoxide is unstable, to raw material | for ketone or | need absolute for aldehyde, sodium methoxide and nitrogen-containing compound, and strictly to control reaction condition, so reaction yield fluctuation is larger, product quality is difficult to ensure that.
For example United States Patent (USP) US-A- 2,827,460 is reported by 2- chlorine-2-methyl-1-(4-chlorophenyl)- 1- acetone and sodium methoxide reaction generation epoxide-2-methoxyl group of 3,3-dimethyl-2- (4- chlorophenyls)Polyethylene oxide intermediate, the intermediate reacts 22 hours at a reflux temperature with morpholine again, obtains 2- methyl isophthalic acids-(4- chlorophenyls)- 2- morpholine -1- acetone.Its
Reaction scheme sees below formula:
Figure IMGF000003_0001
Because the patent does not report yield, inventor proves by experiment:As free alkali in sodium methoxide is too high, in morpholine, water content is too high can all have a significant impact to reaction;In the case of the raw material absolute of reaction, epoxide reacts 22 hours at a reflux temperature with morpholine can then generate more accessory substance.
In addition, Japan Patent JP 63,192,744th, United States Patent (USP) US 3,465,039th, US 3,314,970, former Soviet Union's patent SU 225,203, SU 230,827. ZA 6801749, Stefanescu, Paul is in Rev. Chim. (Bucharest) (1968), 19 (11), 639 and Hahn, Hob- Gyu et al. report such reaction in Han'guk Nonghwa Hakhoechi (1997), 40 (2) 139.
In summary, carbonyl is prepared using direct method or epoxy intermediate method《- substitution nitrogen-containing compound, which all exists, to be selected feed quality requirements height, reaction temperature height, reaction time length, reaction orientation Selecting property difference and the defect such as yield is relatively low.The disclosure of invention
The present invention is on the basis of above method Shortcomings are summarized, to be found by substantial amounts of experiment and dynamic trace analysis, in the presence of having lewis acid, for ketone or《- halogenated aldehyde first can form complex compound with lewis acid, and under very low Warm degree, the complex compound can also be generated.Due to "-halogenated ketone or《- halogenated aldehyde and lewis acid formation complex compound, and make-position!The reactivity of atom is greatly increased, so as to improve "-| the selectivity of the heterocyclic compound reaction for ketone or-halogenated aldehyde with primary amine, secondary amine or containing nitrogen-atoms, extraordinary effect is achieved, so as to complete the present invention.
