Cross-coupling reactions of indium organometallics with 2,5-dihalopyrimidines: synthesis of hyrtinadine A.
Org. Lett. 10(17) , 3745-8, (2008) The palladium-catalyzed cross-coupling reaction of triorganoindium reagents (R3In) with 5-bromo-2-chloropyrimidine proceeds chemoselectively, in good yields, to give 5-substituted-2-chloropyrimidines or 2,5-disubstituted pyrimidines using 40 or 100 mol % of R... |

Improved synthesis of 2,2'-bipyrimidine.
J. Org. Chem. 67(18) , 6550-2, (2002) A high-yield synthesis was developed for the preparation of 2,2'-bipyrimidine (1) using the Ullmann coupling of 2-iodopyrimidine. The new procedure was also used for the preparation of 4,4',6,6'-tetramethyl-2,2'-bipyrimidine (2) and 5,5'-dibromo-2,2'-bipyrimi... |
