A short and efficient route to synthesis of a series of N-dichloroacetyl diazabicyclo derivatives has been developed. The compounds were obtained by cycloaddition of levulinic acid or ester with diamine, followed by acylation with dichloroacetyl chloride. All products were characterized by IR, 1H NMR, 13C NMR, MS, and elemental analysis. The single crystal of compound 4c was determined by X-ray crystallographic analysis. All compounds were tested for their herbicide safeners activity of protecting maize from injury with acetochlor. [ABSTRACT FROM AUTHOR]

A facile synthetic route was developed to N-dichloroacetyl-2,3-dihydrobenzoxazole derivatives 3 by cycloaddition of 2-amino-phenol ( 1) with dichloromethane and acylation of the resultant intermediate 2,3-dihydrobenzoxazole 2 with dichloroacetyl chloride. The structures of the compounds were characterized by IR, 1H NMR, and 13C NMR spectroscopy and elemental analysis. The preliminary biological tests showed that products 3 could protect maize against injury caused by acetochlor to some extent. [ABSTRACT FROM AUTHOR]
