Regioselective cationic reduction of 2-aryl-1-N-(ethoxycarbonyl)enamines to 2-arylethylamine carbamates
摘要:
2-Aryl-1-N-carboalkoxyenamines (enamides) are selectively reduced to the corresponding 2-arylethylamine carbamates by Et3SiH in the presence of CF3COOH in excellent yields. The reduction proceeds by addition of hydride at C-1 and the rate-limiting step involves proton transfer from CF3COOH. This reduction is useful for preparation of isotopically labeled arylethylamines. (C) 2001 Elsevier Science Ltd. All rights reserved.

identified as a new structural motif for obtaining potentinhibitors of human mast cell chymase. For example, 1-naphthyl derivative 5f had an IC50 value of 29 nM and (E)-styryl derivative 6g had an IC50 value of 3.5 nM. An X-ray structure for 5f.chymase revealed key interactions within the enzyme active site. Compound 5f was selective for inhibiting chymase versus eight serine proteases. Compound 6h

Methods of imaging tissue of a mammal which expresses chymase include administering to the mammal an effective amount of a radiolabeled chymase inhibitor. Radiopharmaceuticals that may be used in diagnostic imaging and therapeutic treatment of disease characterized by expression of chymase have the structure of Formula I:
