Lithiation and Electrophilic Substitution of Dimethyl Triazones.
نویسندگان
چکیده
The lithiation and electrophilic substitution of dimethyl triazones is described. Directed lithiation or tin-lithium exchange of dimethyl triazones afforded the corresponding dipole stabilized nucleophiles that were trapped with various electrophiles. Keto-triazone derivatives accessed by acylation of such nucleophiles were readily converted to the corresponding imidazolone heterocycles.

Treatment of 1,4,4-trimethyl-3,4-dihydroquinolin-2(1H)-one (2) with lithium diisopropylamide (LDA) followed by a wide range of electrophiles give the corresponding 4,4-dimethyl-3-substituted-3,4-dihydroquinolin-2-ones (3-13), providing a very mild electrophilic substitution of the 4,4-dimethyl-1,2,3,4-tetrahydroquinoline core.

Protonation of the highly reactive 1:l intermediate produced in the reaction between triphenylphosphine and dimethyl acetylenedicarboxylate by 2- hydroxyacetophenone leads to vinyltriphenylphosphonium salt, which undergoes aromatic electrophilic substitution reaction with the conjugate base to produce compounds 4,5, and 6 in 1 : 1.2:0.5 ratios

Asymmetric lithiation of substituted benzylamines, N-Boc-pyrrolidine, or N-Boc-indoline using Beak's methodology was followed by electrophilic quench with trialkylboranes. The resulting borate intermediates rearrange with concomitant C-N bond breakage to give, after oxidation, chiral secondary alcohols with high enantioselectivity.

An efficient synthesis of 2-heteroarylazulene derivatives was established via electrophilic substitution. The reaction of 6-dimethylamino-1,3-di(methylthio)azulene (1a) with the triflate of N-containing heteroarenes proceeded in the presence of excess heteroarenes to afford the corresponding 2-dihydroheteroarylazulene derivatives 3−7. The 2-dihydroheteroarylazulene derivatives were readily conv...
متن کاملLithiation-electrophilic trapping of N-sulfonyl-activated ethylene aziridines.
A detailed study on the lithiation-electrophilic trapping of N-sulfonyl ethylene aziridines is described. The optimum results required use of a N-2,4,6-tri-iso-propylbenzenesulfonyl activating group and lithiation using 3 equiv. of s-BuLi-PMDETA for 1 minute before addition of the electrophile. In situ trapping with Me3SiCl was also successful. Electrophilic trapping with aldehydes provided a s...
