The present invention relates to modulators of muscarinic receptors. The present invention also provides compositions comprising such modulators, and methods therewith for treating muscarinic receptor mediated diseases.
EnantioselectiveC(sp3)−H activation in simple amides has been achieved by using palladium(II) catalysis with a chiral sulfoxide-2-hydroxypridine (SOHP) ligand. We report herein an efficient asymmetric PdII/SOHP-catalyzed β-C(sp3)−Harylation of aliphatictertiaryamides (up to 93 % yield and 99 % ee), in which the SOHP ligand plays a key role in the stereoselective C−H deprotonation-metalation step
