The invention relates to novel phosphoinositide 3-kinase (PI3K) and mammalian target of rapamycin (mTOR) inhibitor compounds of formula (I) and (II), which are conformationally restricted, and for which the meaning of the substituents are listed in the description. Preferred compounds are those wherein X isoxygen, R
1
is morpholino and R
2
is substituted phenyl or heteroaryl. These compounds are useful, either alone or in combination with further therapeutic agents, for treating disorders mediated by lipid kinases.
