✦ Synopsis


The solid-phase synthesis of sultams from resin-bound amino acids is described. The sulfonylation of the resin-bound primary amines afforded the requisite secondary amines, after which the intramolecular Buchwald-Hartwig-type coupling forms the C-S bond. A final alkylation on the sulfonamides followed by cleavage provided the corresponding seven-membered sultams.

A new procedure for the solid-phase synthesis of 2,6-and 2,7-diamino-4(3H)-quinazolinones is described. The method involves coupling of 2,4,6-and 2,4,7-trichloroquinazoline to a solid support via benzyl alcohol type linkers, subsequent displacement of chlorine at C-2 then at the C-6 or C-7 positions
