WebLithium bis (trimethylsilyl)amide is a lithiated organosilicon compound with the formula LiN (Si (CH3)3)2. It is commonly abbreviated as LiHMDS or Li (HMDS) (lithium hexamethyldisilazide - a reference to its conjugate acid HMDS) and is primarily used as a strong non-nucleophilic base and as a ligand. WebLithiation of fluoropyrazine followed by quenching with various electrophiles was successfully achieved and was used to synthesize new pyrazine derivatives. A further lithiation of 2-fluoro-3-substituted pyrazines allowed access to 2,3,6-trisubstituted pyridazine derivatives. As an application, a one-pot synthesis of a quinuclidinylfluoropyrazine has …
