A compound of the formula (I)wherein R represents a straight or branched, primary or secondary acyclic hydrocarbyl C3–C15 group, which can be saturated or unsaturated, or a straight or branched, primary or secondary acyclic hydrocarbyl C3–C15 group, which can be saturated or unsaturated and wherein one or more of hydrogen atoms is replaced with fluorine atom; X represents hydrogen atom or halogen atom,and* denotes chiral center, and salts thereof. The compound is useful for the treatment of diseases mediated by GPR40, in particular type II diabetes. (I)
However, translating this information to a non-biological catalyst is a challenging task. Here, we report a simple and scalable electrostatically tuned phenol (ETP) as an organocatalyst for transferhydrogenation of N-arenes using the Hantzsch ester as a hydride source. The biomimetic catalyst (1–5 mol%) displays potential catalytic activity to prepare diverse tetrahydroquinoline derivatives with good

A boronic acid catalyzed one-pot tandem reduction of quinolines to tetrahydroquinolines followed by reductivealkylation by the aldehyde has been demonstrated. This step-economcial synthesis of N-alkyl tetrahydroquinolines has been achieved directly from readily available quinolines, aldehydes, and Hantzsch ester under mild reaction conditions. The mechanistic study demonstrates the unique behavior
