Various routes were examined for the synthesis of chiral biphenyl species that are substituted at the 2,2‘, 4,4‘ and 6,6‘ positions. Because the biaryl bond is tetrasubstituted, many coupling reactions were not suitable. The most reliable coupling reaction proved to be the Ullmann, which gave the desired product in 82% yield. The products were required as the starting point for the preparation of chiral

The present application provides novel quinazolines and azaquinazolines and pharmaceutically acceptable salts thereof. Also provided are methods for preparing these compounds. These compounds are useful in for co-regulating RAS/RAF/MEK/ERK and PI3K/AKT/PTEN/mTOR pathways by administering a therapeutically effective amount of one or more of the compounds of formula (I), wherein X, Y, T and R4, and R6 to R8' are defined herein, to a patient. By doing so, these compounds are effective in treating conditions associated with the dysregulation of the RAS/RAF/MEK/ERK and PI3K/AKT/PTEN/mTOR pathways. A variety of conditions can be treated using these compounds and include diseases which are characterized by abnormal cellular proliferation. In one embodiment/ the disease is cancer.
