First enantioselective synthesis of mikanecic acid via Diels-Alder cycloaddition mediated construction of chiral vinylic quaternary center
摘要:
Chiral mikanecic acid (1) was synthesized in 74% enantiomeric purity (92% ee after crystallization) via asymmetric Diels-Alder reaction of a novel in situ generated chiral 1,3-butadiene-2-carboxylate (A).
Described are RORγ modulators of the formula (I),
or stereoisomers, tautomers, pharmaceutically acceptable salts, solvates, or prodrugs thereof, wherein all substituents are defined herein. Also provided are pharmaceutical compositions comprising the same. Such compounds and compositions are useful in methods for modulating RORγ activity in a cell and methods for treating a subject suffering from a disease or disorder in which the subject would therapeutically benefit from modulation of RORγ activity, for example, autoimmune and/or inflammatory disorders.

A new, productive synthesis of 3-cyano-2,5-dihydrothiophene-1,1-dioxide (3) is described. This substituted sulfolene serves as a stableprecursor of 2-cyano-1,3-butadiene and can be used in the Diels-Alder reactions without isolation of the unstable diene.
There are described RORγ modulators of the formula (I),
and formula (II)
or stereoisomers, tautomers, pharmaceutically acceptable salts, solvates, or prodrugs thereof, wherein all substituents are defined herein. Also provided are pharmaceutical compositions comprising the same. Such compounds and compositions are useful in methods for modulating RORγ activity in a cell and methods for treating a subject suffering from a disease or disorder in which the subject would therapeutically benefit from modulation of RORγ activity, for example, autoimmune and/or inflammatory disorders.
