| titleOfInvention | One kind has Boc amino barbiturates-cyclohexadiene spiro-compound and its synthetic method |
| abstract | The invention discloses one kind to have Boc amino barbiturates-cyclohexadiene spiro-compound and its synthetic method, belongs to technical field of organic chemistry.Using 1,1- dicyano -1,3- diene 1 and 1,3- dimethyl barbituric acid, Boc is added into reaction system when raw material 1 converts completely for organic base catalytic reaction in organic solvent 2 O, Boc amino barbiturates-cyclohexadiene spiro-compound 4 of the high selectivity with function dough.The synthetic method is applicable to a variety of different types of 1,1- dicyanos 1, and 3- diolefinic compounds 1 have many advantages, such as that raw material is easy to get, is easy to operate, mild condition, reaction yield are high, can expand quantitative response.The method of the present invention is reacted using cycloaddition mode, and Atom economy is good；Using organocatalysis, the use of transition-metal catalyst is avoided, heavy metal pollution is not present in product. |
