One-Pot and Reducible-Functional-Group-Tolerant Synthesis of α-Aryl- and α-Heteroaryl-α-Trifluoromethyl Alcohols via Tandem Trifluoroacetylation and MPV Type Reduction
A tandem reaction consisting of (1) the in situ generation of functionalized aromatic and electron‐deficient heteroaromatic Grignard reagents, (2) trifluoroacetylation with diphenylmethyl trifluoroacetate, and (3) successive Meerwein–Ponndorf–Verley type reductions giving α‐aryl‐ and α‐heteroaryl‐α‐trifluoromethyl alcohols is reported.
The present invention is directed to compounds of formula (I) (I) which are M1 receptor positive allosteric modulators and that are useful in the treatment of diseases in which the M1 receptor is involved, such as Alzheimer's disease, schizophrenia, pain or sleep disorders. The invention is also directed to pharmaceutical compositions comprising the compounds, and to the use of the compounds and compositions in the treatment of diseases mediated by the M1 receptor.
The present invention relates to compounds of formula (I):
and to salts thereof, wherein R1-R6 have any of the values defined in the specification, and compositions and uses thereof. The compounds are useful as inhibitors of TAF1. Also included are pharmaceutical compositions comprising a compound of formula (I) or a pharmaceutically acceptable salt thereof, and methods of using such compounds and salts in the treatment of various TAF1-mediated disorders.
