Condensation of di-O-acetyl (R,R)- and (S,S)-tartaric anhydride with acetals of N-alkylaminoacetaldehyde gave new chiral auxiliaries (1R,5S,7R)- and (1S,5R,7S)-3-alkyl-2-oxo-3-aza-6,8-dioxabicyclooctane-7-carboxylic (RADO(alkyl)-X and SADO(alkyl)-X) derivatives, respectively.The latter could be used to generate the corresponding 1-cyanovinyl esters that add to furan to give readily crystallizable, optically pure Diels-Alder adducts.The method was illustrated by application to the synthesis of (-)-(1S,4S)-7-oxabicyclohept-5-en-2-one.

A protocol for iodine-catalyzed oxidative rearrangement of tertiary and secondary amines has been developed. This metal-free protocol provides an atom-economical, efficient access to synthetically useful a-amino acid derivatives from readily available acyclic and cyclic tertiary or secondary amines.
