EFFICIENT SYNTHESIS OF SECONDARY CARBOXAMIDES WITH ω-SUBSTITUTED ETHYL AND PROPYL GROUPS ON NITROGEN ATOM BY NUCLEOPHILIC RING OPENING OF CYCLIC IMIDATES
An efficient synthesis of secondary carboxamides carrying ω-substituted ethyl and propyl groups on nitrogen atom has been developed which highlights nucleophilic ring opening of 2-methyl-2-oxazoline, 2-methyl-2-oxazine, and their derivatives with (CH3)3SiX and HX (X= Cl, N3, SeC6H5, SC6H5) type reagents.

An acetyl-protected aminoethyl phenyl thioether has been developed to promote C(sp3)-H activation. Significant ligand enhancement is demonstrated by the realization of the first Pd(II)-catalyzed olefination of C(sp3)-H bonds of freecarboxylicacids without using an auxiliary. Subsequent lactonization of the olefinated product via 1,4 addition provided exclusively monoselectivity in the presence of

Reactions of alkenes with di-n-propyl, diphenyl, and dibenzyl disulphide in the presence of lead(IV) salts in trifluoroacetic acid-dichloromethane are described. The products, vicinal trifluoroacetoxy-sulphides, are obtained in higher yields with manganese (III) salts as the oxidant. Alternative reaction conditions with use of iron(III) salts or in the absence of added metal salts are also described
rapid and simple method to access unnatural 2-substituted 5-thio oxazolines has been developed. This methodology is based on a Pummerer reaction followed by an intramolecular nucleophilicsubstitution, which changes the paradigm for the normal use of a base in Pummerer chemistry. We also provide a useful two-step method for the synthesis of the starting material and a mechanistic proposal based on experimental
