greatly sought after because of their significance in medicinal chemistry. Described here is the first general catalytic methodology to access a wide variety of chiral 2‐ and 4‐substituted tetrahydro‐quinolones, dihydro‐4‐pyridones, and piperidones with excellent yields and enantioselectivities, utilizing a single catalyst system.
This invention relates to compounds of the formula ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6 and R.sup.7 are as defined hereinbelow that exhibit activity as immunostimulants.
A derivative, which is useful as a ret kinase inhibitor is described herein. The described invention also includes methods of using the same in the treatment of diseases mediated by inappropriate ret kinase activity.
