Biocatalytic asymmetric synthesis of secondary and tertiary fluorides is performed by the pyruvate aldolase HpcH and its engineered variants, utilizing β-fluoro-α-ketoacids as non-native donor substrates. Rationalization of beneficial mutations and optimization of reaction conditions allowed for the chemoenzymatic preparation of fluorinated synthons with relevance to bioactive natural products and
