AbstractMonochloroacetic acidesters and amides containing carbo- and heterocycles and heterocyclic esters and amides derived from commercial aryloxyacetyl chlorides were synthesized. The structures of the compounds were confirmed by 1Н and 13С spectroscopy. The herbicidalactivity of the substances was studied with respect to mono- and dicotyledonous plants. The relative antioxidant activity of the compounds

Unprecedented chemodivergent Staudinger reactions of secondary phosphine oxides (SPO) have been developed. Reagent-controlled 1- or 2-nitrogen atom exclusions from azides have been achieved. Conversion of a chiral SPO to a phosphinic amide was stereoretentive, and the potassium salt of natural product LL-D05139β was synthesized for the first time.
