After deformylation of 216 using K2CO3/MeOH, the resultant compound (90%, 81% de) was recrystallized from EtOAc to give optically pure 217. Finally, removal of the Cbz group followed by in situ Boc protection gave N-Boc-4-hydroxypipecolic acid methyl ester (204) (>99% ee, >99% de)...

Rearrangement then gives the homologated acid (RCH2CO2H) or its derivative. The conditions for the rearrangement normally involve heating the diazo ketone in an appropriate solvent (depending upon which acid derivative is required), often in the presence of a transition metal catalyst, the most ...
The ortho-formylation of 2-aminopyridines can be effected via the rearrangement of the azasulfonium salt prepared from a 2-aminopyridine, 1,3-dithiane, t-butyl hypochlorite and sodium methoxide 〈74CC685〉. The crude sulfilimine (815) was refluxed in t-butanol containing potassium t-butoxide ...
