What is A new method for the synthesis of mixed orthoesters from O-allyl acetals about?
Two new methods for the synthesis of orthoesters and compounds containing an orthoester moiety (dihydroisoxazoles) are presented. Mixed orthoesters of general formulas RC(OR 1 )(OR 2 ) 2 and RC(OR 1 )-(OR 2 )(OR 3 ) were prepared via addition of ROH (R = Bu or m-methylphenyl) to O-allyl acetals (acrolein acetals: diethyl or cyclic, i.e., 2-vinyl-1,3-dioxanes or dioxolanes). The catalytic systems for these reactions were generated from [RuCl 2 (PPh 3 ) 3 ] and Na 2 CO 3 ; {[RuCl 2 (COD)] x } or {[OsCl 2 (1,5-COD)] x }, PPh 3 , and Na 2 CO 3 . Compounds containing an orthoester moiety (dihydroisoxazoles) were prepared via tandem isomerization of O-allyl acetals (to O-vinyl acetals) catalyzed by ruthenium complexes followed by cycloaddition to in situ-generated 2,6-dichlorophenylnitrile oxide.
Who reads A new method for the synthesis of mixed orthoesters from O-allyl acetals?
It is typically read by researchers, students, and practitioners in Chemistry.
