THE STEREOCHEMISTRY OF THE INTRAMOLECULAR ELECTROPHILIC ATTACK OF AN ALDEHYDE ON A CARBON-TIN BOND
Fleming, Ian,Rowley, Michael
, p. 3181 - 3198 (1986)
The cyclopentane-forming reaction (20-43) of (4RS,5SR)-2,2,4-trimethyl-5-trimetstannylhexanal takes place with retention of configuration at the carbon atom undergoing electrophilic substitution, in contrast to similar cyclopropane-forming reactions (e.g. 47-48), which take place with inversion of configuration.The hydride transfer (24-45) of the 4RS,5RS diastereoisomeric hexanal takes place from a conformation with hydride anti to the stannyl group.In the case of reacions which might have formed four-membered rings, fragmentation takes place (16-28 and 17-30).The presence of a phenyl ring on the carbon carrying the stannyl group interferes with the reactions designed to test the stereochemistry of the SE2 reaction, diverting the reaction to the formation of tetralins (10-26 and 34-38) or benzcycloheptenes (34-37).
SN2″-Selective and Enantioselective Substitution with Unsaturated Organoboron Compounds and Catalyzed by a Sulfonate-Containing NHC-Cu Complex
Zhou, Yuebiao,Shi, Ying,Torker, Sebastian,Hoveyda, Amir H.
supporting information, p. 16842 - 16854 (2018/11/27)
The first broadly applicable strategy for SN2″-selective and enantioselective catalytic substitution is disclosed. Transformations are promoted by 5.0 mol% of a sulfonate-containing NHC-Cu complex (NHC = N-heterocyclic carbene), and are carried
cis-Cinnamic acid selective suppressors distinct from auxin inhibitors
Okuda, Katsuhiro,Nishikawa, Keisuke,Fukuda, Hiroshi,Fujii, Yoshiharu,Shindo, Mitsuru
, p. 600 - 607 (2014/07/08)
The activity of cis-cinnamic acid (cis-CA), one of the allelochemicals, in plants is very similar to that of indole-3-acetic acid (IAA), a natural auxin, and thus cis-CA has long been believed to be an analog of auxin. We have reported some structure-acti
