The present invention relates compounds of formula (I)
wherein A and R
1
are as defined in the specification, pharmaceutical compositions comprising such compounds, and methods of treating conditions and disorders using such compounds and pharmaceutical compositions.
Disclosed herein are compounds of formula (I)
wherein Ring A and R
1
are as defined in the specification. Pharmaceutical compositions comprising such compounds, and methods for treating conditions and disorders using such compounds and pharmaceutical compositions are also disclosed.
Provided herein are compounds, such as a compound of Formula (I), or a pharmaceutically acceptable salt thereof, that are immunoproteasome (such as LMP2 and LMP7) inhibitors. The compounds described herein can be useful for the treatment of diseases treatable by inhibition of immunoproteasomes. Also provided herein are pharmaceutical compositions containing such compounds and processes for preparing such compounds.
in high to quantitative yields via the 1,5-CH insertion reaction of generated magnesium carbenoid intermediates. When this procedure was commenced with acyclic ketones, multi-substituted tetrahydrofurans were obtained in up to a 96% yield. This procedure provides a new and good way for the synthesis of 1-oxaspiro[4.n]alkanes and tetrahydrofurans with the formation of a carbon–carbon bond between a carbenoid
