A convenient method for the synthesis of β,γ-unsaturated amines from alkenes via α,β-unsaturated diphenylsulfonium salts
1,1-Disubstituted and trisubstituted alkenes were converted into the corresponding β,γ-unsaturated amines 4 via three steps: the initial formation of α,β-unsaturated diphenylsulfonium triflates 2 from alkenes and diphenyl(trifluoromethanesulfonyloxy)sulfo
CF2-containing 2-oxazoline ketone compounds and preparation method thereof
The invention provides a method for mildly and efficiently compounding a series of CF2-containing 2-oxazoline ketone compounds under a photocatalysis condition by actively combining difluoroalkylationreaction with carbon dioxide. The method provided by th

Anti-Markovnikov rearrangement in sulfur mediated allylic C-H amination of olefins
Cationic rearrangement reactions usually follow Markovnikov's rule to give more substituted carbocations as stable intermediates. During our study on sulfur mediated allylic C-H amination of olefins, very rare cases of anti-Markovnikov rearrangement from secondary carbocations toward primary carbocations or primary triflates were observed.

2-Arylallyl as a new protecting group for amines, amides and alcohols
Amines, amides and ethers containing 2-arylallyl groups are selectively and easily deprotected with tert-butyllithium. This transformation probably involves a carbolithiation reaction of the styrenyl moiety followed by a β-elimination process. The Royal Society of Chemistry 2005.

SYNTHESIS OF DERIVATIVES OF 3-HYDROXYMETHYL-3-PHENYLAZETIDINE AND ATTEMPTED CONVERSIONS TO 3-PHENYL-1-AZABICYCLOPENTANE OR 3-PHENYL-1-AZABICYCLOHEXANE
The synthesis of eleven new derivatives of 3-hydroxymethyl-3-phenylazetidine and attempts to form the corresponding 1-azabicyclopentane or 1-azabicyclostructure from these are described.
