Dr Ricardo Labes

Ricardo obtained his first degree in chemistry at Regional University of Blumenau (2009, Blumenau, Brazil) then completed a Master in organic chemistry under the supervision of Professor Francisco de Assis Marques at Federal University of Parana (2012, Curitiba, Brazil) and a PhD in the same University working in the development of ligands for the addition of organozinc reagents to carbonyl compounds.

During his PhD Ricardo spent one year as a visiting PhD at Prof Ley’s group in the University of Cambridge working in two main projects, the development of a synthetic methodology to obtain chiral alkynols in continuous flow, by zinc salt mediated stereoselective alkynylation of aldehydes, and the development of an automated multi-step platform to synthetize 2-pyrazolines. Ricardo returned to the Ley group in 2016 as a post-doctoral research associate under an Ely Lilly-funded position for two years.

His current research involves accelerating the preparation of pharmaceutical compounds via the development of machine-assisted reaction sequences and the exploitation of new aminating and oxidizing methodologies using Continuous Flow Chemistry.
