Process for the preparation of C(5)-substituted 1,2-dihydro-5H-chromeno[3,4-f] quinolines |
| abstract |
A method for preparing C(5)-substituted 1,2-dihydro-5H-chromeno[3,4-ƒ]quinolines from a lactol precursor is provided. The method comprises converting the lactol to one of a select number of mixed acetal derivatives, and then treating the acetals with a Grignard reagent. The new process provides products in higher yield and greater purity. Novel intermediates of this method are also claimed. |
