Conjugate Addition/Ireland−Claisen Rearrangements of Allyl Fumarates: Simple Access to Terminally Differentiated Succinates
journal contributionposted on 2008-02-15, 00:00 authored by Cory C. Bausch, Jeffrey S. Johnson
The conjugate addition of dialkylzinc reagents to allyl fumarates with subsequent Ireland−Claisen rearrangement has been accomplished yielding substituted unsymmetrical succinic acid derivatives. This one-pot reaction creates two new carbon−carbon bonds at contiguous stereogenic centers. The reaction proceeds for several alkylzinc reagents and substituted allyl fumarates. The products contain distinguishable functional handles for further manipulation.
