Synthesis of Some Bridgehead-Bridgehead-Disubstituted Bicyclo[1.1.1]pentanes
摘要:
The synthesis of a wide variety of 1,3-disubstituted bicyclo[1.1.1]pentanes is described, with particular emphasis on the generation of a series of S-X-substituted bicyclo[1.1.1]pentyl bromides required for solvolytic studies. Functional group manipulation at the bridgehead was readily accomplished in the majority of cases by radical processes in some instances, transformations were effected via carbanionic-type intermediates.

C(sp2)-C(sp3) cross-coupling of these fragments to afford biaryl isosteres have been scarce. Herein we describe the development of continuous flow-enabled synthesis of bench-stable bicyclo[1.1.1]pentane trifluoroborate salts. Furthermore, we demonstrate the use of metallaphotoredox conditions to enable cross-coupling of these building blocks with complex arylhalide substrates.

The present disclosure relates generally to compounds that bind to Lysophosphatidic Acid Receptor 1 (LPAR1) and act as antagonists of LPAR1. The disclosure further relates to the use of the compounds for the preparation of a medicament for the treatment of diseases and/or conditions through binding of LPAR1, including fibrosis and liver diseases such as non-alcoholic steatohepatitis (NASH), interstitial lung disease (ILD), or chronic kidney disease (CKD).

protocol for achieving decarboxylative cross-coupling (DCC) of redox-active esters (RAE, isolated or generated in situ) and halo(hetero)arenes is reported. This pragmatically focused study employs a unique Ag–Ni electrocatalytic platform to overcome numerous limitations that have plagued this strategically powerful transformation. In its optimized form, coupling partners can be combined in a surprisingly
