The preparation of (α-alkylidene)tetrahydrofurans by tungsten catalyzed decarboxylation of aldol precursors
摘要:
A series of substituted (alpha-alkylidene)tetrahydrofurans was prepared by tungsten catalyzed reaction of substituted hydroxyfuroic acids. These reactions likely involve beta-lactone intermediates which decarboxylate under the reaction conditions, and rates for olefin synthesis correlated with donor properties of substituents at C(4).
The present disclosure relates to compounds of Formula (I) or (II):
and to their prodrugs, pharmaceutically acceptable salts, pharmaceutical compositions, methods of use, and methods for their preparation. The compounds disclosed herein are useful for inhibiting the maturation of cytokines of the IL-1 family by inhibiting inflammasomes and may be used in the treatment of disorders in which inflammasome activity is implicated, such as inflammatory, autoinflammatory and autoimmune diseases and cancers.
