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 (acr
