Studies on Hydrozirconation of 1-Alkynyl Sulfoxides or Sulfones and the Application for the Synthesis of Stereodefined Vinyl Sulfoxides or Sulfones

open access: yes, 2016
The hydrozirconation reaction of 1-alkynyl sulfoxides or sulfones with Cp2Zr(H)Cl in THF at room temperature predominantly gave Z-β-zirconated vinyl sulfoxides or sulfones with excellent regioselectivity.

Synthesis of C2-symmetric bis-indolyl sulfones

open access: yes, 2009
A new class of C2-symmetric bis-indole derivatives with 2,2-linkage has been synthesized from bis-propargyl sulfones. The method involves treatment of the sulfones with catalytic amount of triethylamine to form the indole derivatives presumably via the ...

Spatial structure of α-halogen-substituted sulfones [PDF]

open access: yes, 1981
1. Conformational equilibrium between the gauche- and trans-forms is attained in α-halogenated sulfones with the gauche-form predominating. 2. The position of the aryl radical in α-haloaryl sulfones is close to interfering with.

Vinyl sulfones: selective and tunable covalent warheads against challenging enzyme targets [PDF]

open access: yesExploration of Drug Science
Over the past several decades there has been a growing recognition of the role that covalent drug candidates have played in the drug development process. With this recognition, compounds that are capable of selectively and irreversibly inactivating their
