Abstract
The present invention discloses a kind of synthetic method of coumarin-pyrrole compound, in reaction solvent, with 4-aminocoumarin compounds and two replaced acetylene compounds for raw material, under palladium (II) catalysis, oxygenant effect, be obtained by reacting coumarin-pyrrole compound.Cheaper starting materials of the present invention is easy to get, and reaction conditions is gentle, and synthetic method route is easy, and Atom economy is high, has good prospects for commercial application.
Description
Technical field
The invention belongs to organic compound process application technical field, be specifically related to a kind of coumarin-pyrrole compound synthetic method.
Background technology
Because nitrogen heterocyclic is prevalent in natural product and medicine, be people's priority fields of studies.As everyone knows, pyrroles is Five-membered Heterocyclic Compounds, and many drug molecules comprise this type of skeleton, therefore in pharmaceutical chemistry, are used as basic structural unit, such as formula A, the trade names sold by Pfizer is the blood lipid-lowering medicine atorvastatin (Atorvastatin) of Lipitor
1, the cancer cells different to many kinds have cytotoxicity and the topoisomerase I 60 of the mankind had to the Lamellarin D (LamellarinD) of strongly inhibited effect
2, there is NSAID (non-steroidal anti-inflammatory drug) (NSAID) zomepirac (Zomepirac) of antipyretic effect
3with potential cancer therapy drug
4.
The several drug molecule containing pyrrole structure unit of formula A.
The method of many synthesis pyrroles is reported.Traditional method has Knorr, Paal-Knorr and Hantzsch reacts.Although these methods effectively can synthesize pyrrole derivative, still there is many obvious defects in the reaction of these classics, and the utilization ratio as starting raw material is low, reactions steps is many, severe reaction conditions etc., and these all limit the use range of above method.Except traditional method, transition metal-catalyzed cycloaddition reaction is mainly used in the synthesis of present pyrrole derivative, as shown in the formula B(a) shown in, the active C of aromatic ring-the orienting group (DG) on H key produces the base pyrrole derivative of different replacement with alkynes to utilize Rh (III) or Ru (III) catalyzed oxidation to be coupled.Although the introducing of orienting group achieves huge progress, need through polystep reaction, the synthesis of azole compounds is more prone to the one-step synthesis B(b avoiding using orienting group).
Present invention achieves Pd(II) catalyzed oxidation cycloaddition " lock "-auxiliary trans-enamine and alkynes one step build coumarin-pyrrole compound, synthetic method route of the present invention is easy, reaction conditions is gentle, atom economy type is high, usefulness is superior, achieve the breakthrough of this system chemosynthesis, and promote that the profound level of this system related drugs chemical research is expanded.
Formula B. utilizes active C-and H key prepares the synthetic schemes of pyrroles.A) orienting group (DG) secondary path; B) " lock " secondary path (omnidirectional substituting group).
Summary of the invention
