	Title	Enantioselective Catalysis, 122 [1] Synthesis of New Optically Active 3.5-DinitrosalicyloxazoIines
	Abstract	New optically active 3,5-dinitrosalicyloxazo-lines, derived from 3,5-dinitrosalicylonitrile and the chiral aminodiols (lS,2S)-(+)-2-am ino-l-phe-nyl-l,3-propanediol, (2S)-(-)-2-amino-l,l,4,4-te-traphenyl-l,4-butanediol and (2S)-(-)-2-amino-l,l-diphenyl-l,3-butanediol, were prepared and used as in situ catalysts for enantioselective cyclo-propanation reactions.

	Title	Enantioselective Catalysis, 120 [1] New Optically Active Pyrrole-oxazolines
	Abstract	14 new optically active pyrrole-oxazolines were synthesised from 2-pyrrole-carbonitrile or methyl 2-pyrrole-carboximidate and chiral amino alcohols. Their use in copper-catalysed enan tioselective cyclopropanation reactions gave only low optical yields (3-14%ee).
