The present invention relates to compounds of formula (I): and pharmaceutically acceptable salts, stereoisomers or tautomers thereof which are inhibitors of the Sonic Hedgehog pathway, in particular Smo antagonists. Thus the compounds of this invention are useful for the treatment of diseases associated with abnormal hedgehog pathway activation, including cancer, for example basal cell carcinoma, medulloblastoma, prostate, pancreatic, breast, colon, bone and small cell lung cancers, and cancers of the upper GI tract.

unactivated alkyl iodides employing a fac‐Ir(ppy)3‐catalyzed radical aminocarbonylation protocol has been developed. Using a two‐chambered system, alkyl iodides, fac‐Ir(ppy)3, amines, reductants, and CO gas (released ex situ from Mo(CO)6), were combined and subjected to an initial radical reductive dehalogenation generating alkyl radicals, and a subsequent aminocarbonylation with amines affording a
A straightforward synthesis of amides, ureas, and esters is reported by visible-light cross-dehydrogenating coupling (CDC) of aldehydes (or amine carbaldehydes) and amines/R-OTBS ethers by photoredoxcatalysis. The reaction is found to be general and high yielding. A plausible mechanistic pathway has been proposed for these transformations and is supported by appropriate controlled experiments.

Alkanes (or cycloalkanes) and CO in the presence of superelectrophilic systems CX4·2AlBr3 (X = Cl, Br) have been applied for the first time as equivalents of acylium salts in one-pot selective syntheses of amides from amines.
