Metal‐Catalyzed C(sp2)–H Bond Functionalization of Indolinone‐ and Indanone‐Type Chemical Platforms En Route Toward Late‐Stage Functionalization

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 8, 15 April 2026.
An in‐depth survey dealing with the aromatic C—H bond functionalization of biologically‐relevant scaffolds featuring the indolinone and indanone core is discussed as they are unique aromatic scaffolds that are 1,2‐doubly fused with small five‐membered rings.

Characterization of the extracellular lipase of Bacillus subtilis and its relationship to a membrane-bound lipase found in a mutant strain [PDF]

open access: yes, 1979
Bacillus subtilis CMK33 is a mutant that is more osmotically fragile than the wild type when it is converted to the protoplast form. The protoplasts of this mutant contain a membrane-bound lipase, which is not found in protoplasts of the wild type ...

Inhibitors of \u3cem\u3eN\u3csup\u3eα\u3c/sup\u3e\u3c/em\u3e-acetyl-l-ornithine Deacetylase: Synthesis, Characterization and Analysis of their Inhibitory Potency [PDF]

open access: yes, 2010
A series of N α-acyl (alkyl)- and N α-alkoxycarbonyl-derivatives of l- and d-ornithine were prepared, characterized, and analyzed for their potency toward the bacterial enzyme N α-acetyl-l-ornithine deacetylase (ArgE).

Perfluoro (Imidoylamidine) diamidines [PDF]

open access: yes, 1986
Perfluoroether triazine elastomers having improved properties are prepared from oligomeric imidoylamidines that were in turn, prepared by the process of: (1) reacting a perfluorodinitrile with liquid ammonia to yield a perfluorodiamidine, (2) isolating ...

Direct synthesis of acyl fluorides from carboxylic acids using benzothiazolium reagents

open access: yesBeilstein Journal of Organic Chemistry
2-(Trifluoromethylthio)benzothiazolium triflate (BT-SCF3) was used as deoxyfluorinating reagent for the synthesis of versatile acyl fluorides directly from the corresponding carboxylic acids. These acyl fluorides were reacted with amines in a one-pot protocol to form different amides, including dipeptides, under mild and operationally simple conditions
