Derivatives of chiral chloro jade poet pebble is disclosure is manufacturing method. The present invention refers to, chiral organic catalyst in the presence, (E)-2-( (E)-2-arylnitroethene [...]) isoindoline chloro 3-derivatives and-2-on (3-chloroindoline-2-one) derivatives characterized in that reaction.

A new methodology was developed for the synthesis of enantiomerically enriched 3,3-disubstituted 3-chlorooxindoles 3 via a Michael addition of 3-chloroxindoles to nitroolefins 2, catalyzed by chiral squaramide 10. Products with adjacent quaternary-tertiary centers were isolated in excellent yields (up to 99%), high diastereoselectivities (up to 11:1), and enantiomeric purities (up to 92%). This is the first example where 3-chloroxoindoles 1 have been used as nucleophiles in a highly stereoselective organocatalytic reaction.
