A general chemo-enzymatic approach to synthesize both enantioenriched trans-3-alkoxyamino-4-oxy-2-piperidones, which are important scaffold for various naturally occurring alkaloids, is reported. To this end, a selective transition-metal-free dual C

Synthesis.
The selective and dual C(sp3)–H oxidation of N-heterocycles to their corresponding 3-alkoxyamino lactams mediated by TEMPO oxoammonium cation (TEMPO+) is turning into a convenient nonmetallic strategy for the rapid functionalization of piperidines

An asymmetric total synthesis of stereoisomers of a putative structure of 3-hydroxy-2-piperidone alkaloid derivative is described. This route is not only concise and efficient but also is achieved under an environmentally friendly approach. To this e

One of the major challenges in organic synthesis is the activation or deconstructive functionalization of unreactive C(sp3 )-C(sp3 ) bonds, which requires using transition or precious metal catalysts. We present here an alternative: the deconstructiv

Highlighting the recently established methodology for the direct synthesis of glycidic amides from tertiary allyl amines, the synthesis of the enantiomers of tedanalactam were completed in two steps from the corresponding chiral dihydropiperidine. Ad

New approaches to the synthesis of alkaloids through the straightforward functionalization of C(sp3)–H and C(sp2)=C(sp2) bonds of simple five- and six-membered-ring N-heterocycles are highlighted. The direct functionalization of pre-existing N-hete

An anodic electrochemical deamination of 3-alkoxyamine lactams to 3-hydroxy lactams was developed. The electrochemical transformation was achieved by using reticulated vitreous carbon (RVC) and stainless-steel electrodes in aqueous ethanolic solution
