REACTION OF (<i>E</i>)-PHENYL 2-PYRIDYL KETONE<i>O</i>-ACYLOXIMES (PPAO) WITH GRIGNARD REAGENTS. A CONVENIENT AND HIGHLY CHEMOSELECTIVE SYNTHESIS OF KETONES
The reaction of (E)-phenyl 2-pyridyl ketone O-acyloximes (PPAO) with Grignardreagents was found to be widely applicable to the chemoselective synthesis of various ketones in good yields under mild conditions.
Compounds of the invention are useful in inhibiting carboxypeptidase U and associated thrombotic occlusions having the structure (I) and pharmaceutically acceptable salts thereof, wherein t is N or N(R2'), u is C(R3) or N(R2'), and v is C(R2), N or N(R2), provided that, 1) when t is N and u is C(R3), then v is N(R2); 2) when t is N and u is N(R2'), then v is C(R2), and 3) when t is N(R2') and u is C(R3), then v is N or N(R2).
