Novel methods for allylic amination by an intramolecular nitroso ene reaction
Published 2013“…We aimed to establish efficient single-step intermolecular C-H amination reactions, to give 1,2 and 1,3 heteroatom functionalised molecules, and to develop the capacity for enantioselective induction in this reaction, if possible. …”

Novel synthetic applications of N-acyliminium ions toward β-turn mimetics and naturally occurring alkaloids
Published 2007“…The application of this novel methodology in target synthesis has been demonstrated by the manipulation of chiral building blocks such as (3). The removal of functional groups has allowed assess to therapeutically active natural products including (+)-crispine A (4) and (+)-harmicine (5), whilst the exploitation of their existing functionality has been utilized to form complex β-turn peptide mimics, such as (6). …”

Studies in isoquinoline chemistry relating to morphine analgesics
Published 1978“…This latter ring closure has been found not to take, place and the former route also did not prove satisfactory. The synthesis of ring-A bridged isoquinolines has been studied. Although thermal isomerisation of 2,5-dihydrophenylacetamides to give conjugated dienes followed by Diels–Alder reaction met with limited success, the Diels–Alder reaction of 1,2,3,4,7,8-hexahydro-6-methoxy-2-methylisoquinoline has been achieved with methyl vinyl ketone, phenyl vinyl ketone and 2-chloroacrylonitrile. …”

Studies in the chemistry of benzobicyclo systems
Published 1972“…Thus, for example, 1-N, N-dimethylamino-tetrafluorobenzobarrelene gives 2,3,4,5- tetrafluoro-k'-N, N-dimethylaminobiphenyl in high yield and 1,2,3,1- tetrafluoro-5,8-dihydro-5,8-N-(-methyl)-iminonaphthalene affords 2'- (2,3,4,5-tetrafluorophenyl)-N-methyl. pyrrole. …”

Design, synthesis, conjugation and reactivity of novel trans,trans-1,5-cyclooctadiene-derived bioorthogonal linkers
Published 2020“…This two-step strategy relies on the use of new bifunctional TCO linkers (5a–11a) for IEDDA reactions, which can be synthesized via 1,3-dipolar cycloaddition of (E,E)-COD 1 with different azido spacers (5–11) carrying an electrophilic function (NHS-ester, N-succinimidyl carbonate, p-nitrophenyl-carbonate, maleimide) in the ω-position. …”
