The efficient desymmetrization of N-(2-tert-butylphenyl)maleimides was realized by means of a Michael addition reaction of a series of carbon nucleophiles generating the corresponding axially chiral succinimides in high yields. The use of (DHQD)2Pyr as catalyst was fundamental to achieve the remote control of the stereogenic chiral axis with the concurrent construction of adjacent quaternary and tertiary stereocenters.

Abstract
The efficient desymmetrization of N-(2-tert-butylphenyl)maleimides was realized by means of a Michael addition reaction of a series of carbon nucleophiles generating the corresponding axially chiral succinimides in high yields. The use of (DHQD)2Pyr as catalyst was fundamental to achieve the remote control of the stereogenic chiral axis with the concurrent construction of adjacent quaternary and tertiary stereocenters.File in questo prodotto:
