Alkaloid syntheis via novel azabicycles.

Boynton, Carole M.Sheffield Hallam University (United Kingdom).1988

… which resulted in the formation of 5,6,7,7a-tetrahydro-1-methyl-2-phenylthio-3H-pyrrolizin-5-one in good yields. Desulphurisation gave 5,6,7,7a-tetrahydro-1-methyl-3H-pyrrolizin-5-one which has previously been converted into (+/-)-supinidine. Thus our method constitutes a formal total …

Mechanistic Studies of Donor-Acceptor Cyclopropanes

Chidley, TristanThe University of Western Ontario2015

Cyclopropane 1,1-diesters 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 …

The Multicomponent Synthesis of Pyrroles from Cylcopropane S Using a One Pot Pd(0) Catalyzed Dehydrocarbonylation Protocol

Humenny, William JThe University of Western Ontario2012

… work done by the Kerr group has shown that tetrahydro-1,2-oxazines can be efficiently synthesized using a three component coupling reaction between a hydroxylamine, aldehyde and cyclopropane diester. This affords the desired heterocycle efficiently with a wide variety of substitution. When …
