Alkyl 3-chloropyrrole-2-carboxylates and 2-alkanoyl-3-chloropyrroles are conveniently prepared from 2-alkyl-1-pyrrolines by tetra- and pentahalogenation with N-chlorosuccinimide, subsequent base-induced aromatisation with sodium alkoxides in the corresponding alcohol and final acid hydrolysis of the resulting orthoester or acetal functions into the 3- chloropyrrole. The developed strategy is applied to the synthesis of the trail pheromone of the ant Atta texana.

The present invention relates to pyrimido oxazine derivatives or pharmaceutically acceptable salts thereof, a preparation method thereof, and a pharmaceutical composition comprising the same as an effective component for preventing or treating PI3 kinase-related diseases. The pyrimido oxazine derivatives according to the present invention have excellent selective inhibitory effects on PI3 kinase, and thus may be beneficially used in preventing or treating PI3 kinase-related diseases such as the following: cancers including blood cancer, ovarian cancer, cervical cancer, breast cancer, large intestine cancer, liver cancer, stomach cancer, pancreatic cancer, colon cancer, periotoneal cancer, skin cancer, bladder cancer, prostate cancer, lung cancer, osteosarcoma, fibrous tumor, and brain tumor; autoimmune diseases including rheumatoid arthritis, systemic lupus erythematosus, multiple sclerosis, type 1 diabetes, hyperthyroidism, myasthenia gravis, Crohnandprime;s disease, ankylosing spondylitis, psoriasis, pernicious anemia, and Sjogrenandprime;s syndrome; and respiratory diseases including chronic obstructive pulmonary disease (COPD), rhinitis, asthma, chronic bronchitis, chronic pulmonary inflammatory diseases, silicosis, pulmonary sarcoidosis, pleuritis, alveolitis, vasculitis, emphysema, pneumonia, and bronchiectasis.COPYRIGHT KIPO 2017
