Amidation of unprotected aminoacids has been investigated using a variety of ‘classical“ coupling reagents, stoichiometric or catalytic group(IV) metal salts, and boron Lewis acids. The scope of the reaction was explored through the attempted synthesis of amides derived from twenty natural, and several unnatural, aminoacids, as well as a wide selection of primary and secondary amines. The study also
Highly enantioselective 1, 3-dipolar cycloaddition of 2-arylidene-benzofuran- 3(2H)-ones with imino esters catalyzed by thiourea−quaternary ammonium salts has been developed. This reaction provides efficient construction of a range of chiral spiro[benzofuran-2,3′-pyrrolidine] in high yields (up to 99%) and with good enantioselectivities (up to 99% ee) under mild conditions.

Structural modifications to the peptide deformylase inhibitor BB-3497 are described. In this paper, we describe the initial SAR around this lead for modifications to both the P2' and P3' side chains. Enzyme inhibition and antibacterial activity data revealed that a variety of substituents are tolerated at the P2' and P3' positions of the inhibitor backbone. The data from this study highlights the potential for modification at the P2' and P3' positions to optimise the physicochemical properties. (C) 2003 Elsevier Ltd. All rights reserved.
