Pd-catalyzed C–P coupling of heteroaryl boronic acid with H-phosphonate diester
摘要:
We report herein a novel protocol to construct C-P bond from heteroaryl boronic acid with H-phosphonate diester under Pd-Ag catalyzed system without addition of base. This method, directly using commercial available heteroaryl boronic acid as the starting material, provides a new way to synthesize a variety of useful heteroaryl phosphonates. (C) 2016 Elsevier Ltd.

The present invention provides methods for inhibiting mTOR using pyrazolo[1,5-a]pyrimidine compounds and methods of treatment, prevention, inhibition, or amelioration of one or more diseases associated with mTOR using such compounds.
Ligand-Controlled Palladium-Catalyzed Pyridylation of 1-<i>tert-</i>Butoxycarbonyl-3-iodoazetidine: Regioselective Synthesis of 2- and 3-Heteroarylazetidines
AbstractThe first efficient regioselective pyridylation of 1‐tert‐butoxycarbonyl‐3‐iodoazetidine to produce 2‐ and 3‐heteroarylazetidines under palladium‐catalyzed conditions has been developed. The established direct pyridylation of azetidines affords 2‐ vs. 3‐heteroarylazetidines in moderate to good yields (up to 92%) and with good regioselectivity (up to 98:2) by using different ligands.magnified image
