New series of enantiopure 3,3′-diiodobinaphthol- and 3,3′-diiodobiphenol-based molecules have been synthesized and used as chiral hypervalent iodine oxidation organocatalysts in the α-oxytosylation of propiophenone. When we compared these new organocatalysts to our previous series of 3,3′-diiodo-1,1′-binaphthalene-2,2′-diol-fused maleimides, we have made two important observations: the maleimide moiety is the best moiety for obtaining moderate enantioselectivities, and the presence of an aliphatic substituent on the biaryl part of the catalyst enhances the enantioselectivity.
SELF-IMMOLATIVE SYSTEMS

Page/Page column 11; 26; 27, (2020/05/28)
The present invention is concerned with self-immolative recognition and/or responsive systems for electrophilic compounds, especially alkylating agents, which systems may comprise disclosure or detection of the alkylating agent. The present invention is especially concerned with non-protic triggered self-immolative systems, molecules, and methods, and in particular for detection of non- protic electrophilic agents, and especially alkylating agents, for example alkyl or benzylic halides, which may be found in pesticides or fumigants, or chemical warfare agents.
