Novel acylamino-directed relay disubstitutions realize the sequential difunctionalizations of anilides (1) under mild and metal-free conditions for the first time. This [bis(trifluoroacetoxy)iodo]benzene (PIFA) and BF3·Et2O promoted straightforward reaction produces a series of p-acetoxyl- or p-alkoxyl-o-nitro-N-arylamides (2), which are key scaffolds of various drugs, functional materials, and bioactive molecules. The flexibility with respect to the functional groups in these products affords this novel protocol excellent versatility for synthetic applications.

Arene diazonium tetrafluoroborates can be synthesized from aromatic acetamides via a sequence of deacetylation, diazotation and precipitation, induced by anion exchange. The reaction is conducted as a convenient one-flask transformation with consecutive addition of the appropriate reagents. Exchange of solvents or removal of byproducts prior to isolation of the product is not required. The arene diazonium salts are isolated from the reaction mixture by simple filtration. Two complementary protocols are presented, and the utility of the reaction is exemplified for a synthesis of the diarylheptanoid natural product de-O-methyl centrolobine.
Synthesis, antineoplastic and anthelmintic activities of N-alkyloxycarbonyl-N'-(4-benzyloxy-2-nitrophenyl)thioureas as prodrugs of (6-benzyloxy-1H-benzimidazol-2-yl)carbamic acid ester

Carbalkoxythioureidobenzene derivatives represented by the following formula: STR1 where R is a lower alkyl group having 1 to 4 carbon atoms; R1 is --SR2, --SOR2, --SO2 R2, --OR2, --SCN, --SC(O)NR3 R4, or --M'(CH2)n MR7 where n is 1-4; R2 is lower alkyl having 1 to 6 carbon atoms, cycloalkyl having 3 to 7 carbon atoms, lower alkenyl or lower alkynyl having 3 to 6 carbon atoms, aralkyl or aryl, provided that when R1 is --SO2 R2, R2 is not aralkyl or phenyl; R3 and R4 are independently hydrogen or lower alkyl having 1 to 6 carbon atoms; Y is amino, nitro, acylamino where the acyl portion has 1 to 6 carbon atoms, --NHC(O) (CH2)m COOH where m is 1-6, or --NHC(S)NHCOOR; M and M' are independently O, S or STR2 and R7 is lower alkyl having 1 to 4 carbon atoms or aryl. The R1 substitution is either at the 4- or 5-position. The compounds are useful as pesticides, particularly as anthelmintic and antifungal agents.
