, (2021)
A Noyori reduction of racemic 1-Boc-3-fluoropiperidin-4-one has been achieved under dynamic kinetic resolution conditions that results in a single cis enantiomer being obtained with both diastereo- and enantioselectivity > 90%. This medicinal chemistry building block can be generated on multi-gram scale using the developed conditions to a single enantiomer in a 60% yield after employing a crystallisation procedure.

The first enantioselective route to both enantiomers of cis-1-Boc-3-fluoropiperidin-4-ol, a highly prized building block for medicinal chemistry, is reported. An enantioselective fluorination is employed, taking advantage of the methodology reported by MacMillan, which uses a modified cinchona alkaloid catalyst. In studying the fluorination reaction, we have shown that the catalyst can be replaced by commercially available primary amines, including α-methylbenzylamine, with similar levels of enantioselectivity. The piperidinols are readily crystallized to obtain enantiopure material.
