Convenient synthesis of isoxazolines via tandem isomerization of allyl compounds to vinylic derivatives and 1,3-dipolar cycloaddition of nitrile oxides to the vinylic compounds

A novel effective method for the synthesis of new isoxazolines via tandem isomerization of QCH(X)CH{double bond, long}CH(Y) to QC(X){double bond, long}CHCH2(Y) (Q = RO, RS, R2N, R3Si, etc.; X = H, R, OR; Y = H, R; R = alkyl, aryl) catalyzed by ruthenium complexes and 1,3-dipolar cycloaddition of the latter compounds to arenenitrile oxides is presented. The cycloaddition of QCH(X)CH{double bond, long}CH(Y) to 2,6-dichlorobenzonitrile oxide is also described. The regio- and stereoselectivity of the cycloaddition of nitrile oxide to allyl and 1-propenyl (vinylic in general) compounds is discussed.

Regioselective Protonation of Allylithium Compounds

By varying the general acid, the regioselectivity of the protonation of (triphenylsilyl)allyllithium (1) in diethyl ether in the presence of HMPT can be changed from 9:1 to 1:9 at room temperature.When other aprotic solvents are used, the nature of the lithium salt changes, and the selectivity decreases.The regioselectivity of the protonation of the dithio-stabilized allyllithium 4 by water is highly dependent on the age of the allyllithium solution with α/γ ratios varying from 2.7:1 to 1:3.5. - Key Words: Protonation, regioselective / Allyllithium compound / Allyl anion / General acid / Regioselectivity / Aging

Preparation of (Triphenylsilyl)allyl Anion and (Triphenylgermyl)allyl Anion from 1-Propenyltriphenylsilane and 1-Propenyltriphenylgermane and Their Reactions with Electrophiles

Treatment of 1-propenyltriphenylsilane with n-BuLi in THF-HMPA provides (triphenylsilyl)allyl anion which is identical with an anion derived from 2-propenyltriphenylsilane and base.Generation of (triphenylgermyl)allyl anion is also described.Addition of alkyl halides or carbonyl compounds to these anions gives the corresponding adducts regioselectively.
