Complete diastereofacial selective cycloaddition of new sulfinyl dienophiles (Ss)- and (Rs)-(-)menthyl α-(2-methoxyphenylsulfoxyl)acylate with anthracene under chelation control

New sulfinyldienophiles (Ss)- and (Rs)- (-)menthyl α-(2-methoxyphenylsulfoxyl)acylate were prepared. Cycloadditions with anthracene in dichloromethane proceeded with complete diastereoselectivity under chelation control. Chirality at sulfur controlled dia

Synthesis of N-Hydroxy-α-amino Acids by Alkylation of N-Benzylidene-α-amino Acid Methyl Ester N-oxides

The higher N-benzylidene-α-amino acid methyl ester N-oxides 3c-t were obtained from the lower nitrone esters 3a and b by base induced alkylation in α-position of the N->O-group.The compounds 3 were converted into the N-hydroxy-α-amino acid methyl esters 6 by heating with hydroxylamine hydrochloride in ethanol and into N-hydroxy-α-amino acids 7 with concd. hydrochloric acid. - Compound 3d was, on heating in toluene, converted to methyl 1-aza-7-oxabicycloheptanecarboxylate 8 by intramolecular cycloaddition.
