On the origin of the haouamine alkaloids

(Chemical Equation Presented) Not what it seemed: Careful reinvestigation of the classic Chichibabin pyridine synthesis has provided evidence against a spontaneous tetramerization pathway in the biosynthesis of the haouamine alkaloids. A simple enantioselective synthesis of haouamine A has illuminated its absolute configuration and points towards a phenylalanine-based biosynthesis.

Palladium chloride/tetraphenylphosphonium bromide intercalated clay: New catalyst for cross-coupling of aryl halides with arylboronic acids

A facile method for the preparation of biaryl compounds is described from readily accessible aryl halides and arylboronic acids using palladium chloride/tetraphenylphosphonium bromide intercalated clay as a new catalyst.
