Abstract
The invention discloses an oxacyclo-sulfamide spirocyclic medicament template and a synthesis method thereof. The method comprises the following steps of: first cyaniding and aminating a tetrahydro-4H-pyran-4-one or tetrahydrofuran ketone compound in a one-pot boiling manner; then reducing a cyanogroup into an amino-group; next directly performing ring closing with amino sulfamide to obtain a 2-N substituted oxacyclo-sulfamide spirocyclic medicament template (a target compound I); and finally easily obtaining a 2,5-N disubstituted oxacyclo-sulfamide spirocyclic medicament template (a target compound II), wherein the compound I and the compound II have the structural formulae. The synthesis method of the invention has the advantages of high efficiency and the large-scale preparation of the oxacyclo-sulfamide spirocyclic medicament templates.
Description
Technical field: the present invention relates to a synthesis method of an oxacyclic sulfonamide spirocyclic drug template. Background technique: As early as the 1970s, spirocyclic compounds were found to have biological activity. After more than 30 years of research and development, a variety of spirocyclic derivatives have been confirmed to have promising therapeutic effects, such as anti-depression, inhibition of angiogenesis (anti-tumor), anti-platelet aggregation (anti-thrombosis), and anti-Algia Merz disease (senile dementia), etc. Oxacyclic sulfonamide spiro ring structure 1 contains hydrogen bond acceptors and donors at the same time, and the presence of hydrogen bond acceptors and donors can increase the chance of interaction between the substrate and the target, thus possibly improving the interaction between the substrate and the protein. The degree of binding to the target can increase the activity of the substrate. Due to the unique structure of this type of...
