A one-pot method for the asymmetricsynthesis of tert-butanesulfinyl-protected amines is described. The ketones bd2 are condensed with (R)-tert-butanesulfinamide bd1 and the tert-butanesulfinyl imine intermediates reduced in situ with NaBH4 to afford the sulfinamides bd4 in 66–86% yield and with drs from 90:10 to 97:3 for both aryl alkyl and dialkylketones. Ti(OEt)4 serves as both a water scavenger

Peptoids, oligo-N-substituted glycines, can fold into well-defined helical secondary structures. The design and synthesis of new peptoid building blocks that are capable of both (a) inducing a helical secondary structure and (b) decorating the helices with chemical functionalities are reported. Peptoid heptamers containing carboxamide, carboxylic acid or thiol functionalities were synthesized, and the resulting peptoids were shown to form stable helices. A thiol-containing peptoid readily formed the homodisulfide. providing a convenient route to prepare peptoid helix homodimers.
