Non-Cryogenic, Ammonia-Free Reduction of Aryl Compounds
-
, (2022/03/31)
A method of reducing an aromatic ring or a cyclic, allylic ether in a compound includes preparing a reaction mixture including a compound including an aromatic moiety or a cyclic, allylic ether moiety, an alkali metal, and either ethylenediamine, diethylenetriamine, triethylenetetramine, or a combination thereof, in an ether solvent; and reacting the reaction mixture at from ?20° C. to 30° C. for a time sufficient to reduce a double bond in the aromatic moiety to a single bond or to reduce the cyclic, allylic ether moiety.
Regioselective Transfer Hydrodeuteration of Alkenes with a Hydrogen Deuteride Surrogate Using B(C6F5)3 Catalysis

A regioselective hydrodeuteration of alkenes using monodeuterated cyclohexa-1,4-dienes as surrogates for hydrogen deuteride (HD) gas is reported. The metal-free process proceeds under B(C6F5)3 catalysis presumably by deuteride abstraction to form borodeuteride [DB(C6F5)3]a and highly Br?nsted-acidic Wheland intermediates. Low catalyst loadings (2.5 mol %) are used, and the reaction proceeds at room temperature.
C19 quassinoid model studies: Preparation of trans-perhydroindans via a vinylogous Mukaiyama aldol - Free-radical cyclization route

Aldehyde 9 was prepared in 5 steps from 3,5-dimethylbenzoic acid. Treatment of 9 with ketene acetals 10 and 19 and titanium tetrachloride gave free-radical cyclization substrates 11 and 20 in 67% and 51% yields, respectively. Tri-n-butylstannane-mediated
