Abstract
The invention discloses a synthesis method of divergently oriented azacycles and belongs to the technical field of chemical pharmaceutics and preparation of fine chemicals. By virtue of the synthesis method of divergently oriented azacycle, polysubstituted N-allyl-3-indolal and 3-diazabicyclo[3,1,0] hexanal can be synthesized at one time; sulfonyl triazole catalyzed by metal is decomposed into metal carbine, subsequently, the metal carbine is cyclized so as to efficiently obtain two types of differently structural azacycles, namely N-allyl-3-indolal and 3-diazabicyclo[3,1,0] hexanal. The invention provides a novel technical route for efficiently preparing derivatives of functionalized N-allyl-3-indolal and 3-diazabicyclo[3,1,0] hexanal derivatives. The synthesis method of divergently oriented azacycles has a wide application range in the field of chemical pharmaceutics and fine chemicals.
Description
Technical field
The invention belongs to chemical pharmacy and fine chemistry industry preparing technical field, disperse N-allyl group-3-indolal and the 3-azabicyclic [3 of synthetic guiding, 1,0] hexanal, especially relate to the Cabbeen cyclization of metal catalytic, generate efficiently two kinds of polysubstituted nitrogen heterocyclics, and can effectively control the relative proportion of product.The present invention, for the functionalized nitrogen heterocyclic derivative of efficient preparation provides a new technological line and layout strategy, has wide application at chemical pharmacy and field of fine chemical.
Background technology
Nitrogen heterocyclic is the important organic compound of a large class, and a lot of nitrogen heterocyclics have special chemistry and biological activity, are present in many natural products and drug molecule, are also applied in functional materials.And containing the heterocyclic nitrogen compound organic molecule of high added value especially of aldehyde radical because aldehyde radical can be very easily further derivatize obtain the nitrogen heterocyclic of a lot of other structures.N-allyl group-3-indolal and 3-azabicyclic [3,1,0] hexanal is the very valuable nitrogen heterocyclics of two classes because containing multiple functional group and pharmacophore in its structure, and the preparation method of this two compounds is limited at present, and the method for bibliographical information may be summarized to be following equation substantially:
(1), from indoles 1, through Vilsmeier, formylation obtains 3-indolal 2 (formula 1).
(2), from eneyne 3s, gold catalyst catalyzing oxidation obtains 4 (formulas 2).
(3), from eneyne 5s, metal catalyst catalyzed oxidation obtains 6 (formulas 3).
These methods have certain limitation, are difficult for preparation such as substrate is complicated, and the shortcoming such as substrate narrow range.Consider above shortcoming, the present invention prepares the novel method of two kinds of distinct nitrogen heterocyclics of structure when will setting forth a kind of convenient and general.
Summary of the invention
The object of the invention is to set forth a kind of divergence form nitrogen heterocyclic preparation method, is exactly to have invented an a kind of efficient step to prepare two kinds of nitrogen heterocyclic N-allyl group-3-indolals and 3-azabicyclic [3,1,0] hexanal specifically.
For realizing above-mentioned synthetic object, the present invention adopts following technical scheme, the reaction equation shown in being summarised as: (formula 4).In appropriate solvent, the cyclisation under suitable metal catalyst catalysis of various 1-alkylsulfonyl triazoles 7 obtains N-allyl group-3-indolal 8 and 3-azabicyclic [3,1,0] hexanal 9 after suitable hydrolysis treatment.
