A new class of arylsulfonylethylsulfonylmethyl oxazolines and thiazolines were prepared using multistep, one-pot methodologies exploiting lanthanide alkoxides and under microwave irradiation. The microwave method provides an excellent approach in a single step with high yields.

, (2008/06/13)
Selective MMP-13 inhibitors are fused pyrimidinones of the formula or a pharmaceutically acceptable salt thereof, wherein: W, together with the carbon atoms to which it is attached, form a 5-membered ring diradical X is O, S, SO, SO2, NR5, or CH 2; B is O or NR5; or A and B are taken together to form--C≡C--; R1, R4, and R 5 are hydrogen, alkyl, alkenyl, alkynyl, (CH2)n aryl, (CH2)n cycloalkyl, C1-C6 alkanoyl, or (CH2)n heteroaryl; R2 and R3 are hydrogen, alkyl, alkenyl, alkynyl CN, NO2, NR 4R5, (CH2)n cycloalkyl, (CH2) n aryl, or (CH2)n heteroaryl; R2 may further be halo; n is an integer of from 0 to 5; and R4 and R5 when taken together with a nitrogen to which they are both attached complete a 3-to 8-membered ring containing carbon atoms and optionally containing O, S, or N, and substituted or unsubstituted; with the proviso that R1 and R3 are not both selected from hydrogen and C1-C6 alkyl.

The feasibility of cycloalkylation reactions in the presence of Friedel-Crafts catalysts was demonstrated in a nimber of aryl hydroxyalkyl sulfides (1-5), and benzyl hydroxyalkyl sulfides (6-7).Treatment of compounds (1-7) with Friedel-Crafts catalysts gave diaryl disulfides, diaryl sulfides, arene thiols, chlorohydrins, aryl chloroalkyl sulfides, aryl alkenyl sulfides and cyclization products.It is noteworthy to mention that cyclization products were isolated only in cases where the hydroxyl group is linked to a tertiary carbon atom as in compounds 3 and 7.A suitable reaction pathway is suggested to rationalize the formation of the various reaction products.
