An easy and efficient synthetic approach to the title compounds is described, proceeding smoothly in the presence of molecular iodine. The metal-free protocol is insensitive to air moisture, is operationally simple and broadly applicable to a variety of N,4-disubstituted quinazoline-2-amine and oxides and synthesized in good to excellent yields starting from readily available inexpensive precursors.

A highly efficient method for the C–N bond formation via 2 mol% of molecular iodine-catalysed amidation reaction of benzylic and allylic alcohols with carboxamides or sulfonamides in MeCN is described, giving the corresponding substituted amides and allylic amides in moderate to excellent yields. The significan features of the procedure include mild and metal-free reaction conditions, operational simplicity, inexpensive reagents, short reaction time, and good yields.
