Donor-Acceptor Cyclobutanes and Their Application for Heterocycle Synthesis and Progress Towards Biselide A
… of each other. Under Yb(OTf)3 catalysis donor-acceptor cyclobutanes undergo a formal [4+2] cycloaddition with aldehydes to generate tetrahydropyrans exclusively in a cis disposition. Activated aldehydes were generally well tolerated giving tetrahydropyrans in moderate to good yields (51 - …

Mechanistic Studies of Donor-Acceptor Cyclopropanes
… have been investigated as a source of donor-acceptor cyclopropanes, providing an understanding of the mechanism of reaction between these cyclopropanes and nitrosoarenes, as well as azo dicarboxylates. Cross-over experiments have been utilized to provide key pieces of experimental …
