Widegren, Magnus B.,Clarke, Matthew L.
supporting information, p. 2654 - 2658 (2018/05/17)
A manganese-catalyzed hydrogenation of esters has been accomplished with TONs up to 1000, using cheap, environmentally benign, potassium carbonate and simple alcohols as activator and solvent, respectively. The weakly basic conditions lead to good functional group tolerance and enable the hydrogenation of enantiomerically enriched α-chiral esters with essentially no loss of stereochemical integrity.

The present invention relates to a process for preparing enantiomerically enriched 3-hydroxymethylpiperidine and in particular of the S-enantiomer of (S)-3-hydroxymethyl- piperidine in high chemical and optical purity. The invention also relates to extremely pure (S)-3-hydroxymethylpiperidine and (R)-3-hydroxymethylpiperidine.

The present invention provides a compound represented by the general formula: [wherein Ring A represents an optionally substituted 5- to 8-membered ring, Ring B represents a further optionally substituted 4- to 10-membered ring, Ring C represents a further optionally substituted benzene ring, X1 represents carbon atom, X2 represents a carbon atom, an oxygen atom, etc., W represents a nitrogen atom, etc., Y11 represents a group represented by the formula CR2R3' (wherein R2 represents a hydrogen atom, a cyano group, a nitro group, etc., and R3' represents a hydrogen atom, a cyano group, a nitro group, etc., respectively), Y21 represents a group represented by the formula CR4R5' (wherein R4 represents a hydrogen atom, a cyano group, a nitro group, etc., and R5' represents a hydrogen atom, a cyano group, a nitro group, etc., respectively), etc., and R1 represents an electron-withdrawing group, respectively. The formula represents a single bond or a double bond] or a salt thereof, which is useful as an androgen receptor modulator.
