Telescoped Synthesis of Stereodefined Pyrrolidines
摘要:
Telescoped and one-pot olefination/asymmetric functionalization approaches to disubstituted pyrrolidines (dr up to 99:1, up to 99% ee) have been developed using commercially available tetramisole (0.1 to 5 mol %). Using OTMS-quinidine as the Lewis base gives preferential access to an anti-configured pyrrolidine in high enantioselectivity.
2-alkoxycarbonyl, 2-cyano, 2-phenylsulfonyl N-alkylaziridines was elaborated via intramolecular nucleophiles substitution of chloride in 1-N-chloro-2-alkoxycarbonyl (cyano, phenylsulfonyl) ethyl amines. These substituted N-chloroamines are readily erasable via N-chlorination of the adducts of primary amines to Michael acceptors.
The straightforward access to peptoid-based multivalent thioglycoclusters displaying 1-thio-β-d-galactose or 1-thio-α/β-d-mannose and their evaluation towards two bacterial lectins are described.
cyclization of α,β-tetrapeptoids. The ctct amide sequence revealed in the crystal structure of the 14-membered cyclotetrapeptoid 8 is also the most populated conformation in solution and is reminiscent of the predominant amide arrangement of the 12-membered cyclic tetrapeptides (CTPs).
