The first series of alkali dipyrrinato complexes
The first series of alkali dipyrrinato complexes is reported, encompassing lithium, sodium, and potassium salts of meso-unsubstituted and meso-aryl-substituted derivatives. By varying the substituents at the meso position, ...
Asymmetric oxidation of 2-(arylsulfenyl)pyrroles
The asymmetric oxidation of prochiral 2-(arylsulfenyl)pyrroles has been investigated. A marked electronic effect within the substrate significantly influenced the degree of enantioselectivity obtained, with very high enantio ...
Investigations into the nucleophilic meso-substitution of F-BODIPYs and improvements to the synthesis of 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene.
A series of three F-BODIPYs, with varying levels of steric crowding about the meso-position were selected to investigate nucleophilic meso-substitution of F-BODIPYs. The synthesis of one of these F-BODIPYs, 4,4-difluor ...
Recent developments in the aerobic oxidation of alcohols.
A review. Both heterogeneous and homogeneous catalysts are covered. The use of various supports is discussed.
Asymmetric Pauson-Khand reactions using camphor-derived chelating thiols as chiral controllers.
To demonstrate a reliable and efficient asym. version of the Pauson-Khand reaction with the aid of a camphor-derived chelating thiol as a chiral auxiliary. Research published by I. Marchueta, E. Montenegro, D. Panov, M. ...
Synthesis and properties of ring-deactivated deuterated (hydroxymethyl)pyrroles.
The title research of A. D. Abell, B. K. Nabbs, and A. R. Battersby (1998) is reviewed with commentary and 7 refs. [on SciFinder(R)]

Amido-Functionalized Prodigiosenes: Synthesis and Anticancer Properties.
Amido-functionalized prodigiosin-derived compds., such as I [R = Ph, CH2Ph, CH2CH:CH2, CH2Me, CMe3], were synthesized via a robust and efficient synthetic route. These compds. were then evaluated against 60 human cell lines ...
Improved Synthetic Route to C-Ring Ester-Functionalized Prodigiosenes
An efficient, optimized, and scalable process for the synthesis of C-ring ester-functionalized prodigiosenes has been developed by (i) exploiting a silylative Mukaiyama aldol strategy for the condensation of alkyl ...
