Therefore acceptor cyclopropanes 1 will be ring opened by nucleophiles N to provide products like 2 (homo Michael addition) as depicted in Eq. 1. On the other hand, electrophiles E+ cleave donor activated cyclopropanes 3 affording adducts 4 or 5 which demonstrates that the cyclopropane serves as a homoenolate equivalent in this sequence (Eq. 2). Seebach consequently classified these methods as umpolung with the cyclopropane trick 4. ... [Pg.75]

Enamine catalysis is based on the ability of primary or secondary amines to displace the equilibrium of a carbonyl compound to the more reactive enamine (Scheme 11.2, eq 2). The subsequent enamine has its highest occupied molecular orbital (HOMO) increased, facilitating the attack on a suitable Michael acceptor. [Pg.320]
