Lck, one of eight members of the Src family of tyrosine kinases, is activated after T cell stimulation and is required for T-cell proliferation and interleukin (IL)-2 production. Inhibition of Lck has been a target to prevent lymphocyte activation an

Tetrahedron Letters. 38:1241-1244
A simple and efficient process has been developed for the direct conversion of benzamides and thiobenzamides into tertiary carbinamines. A synthesis of benzonitriles from simple benzamides and a thiobenzamide is also described.
