A cascade Diels-Alder reaction coupled with an oxidative aromatization reaction was developed and applied to a chiral 2-pyrone for the synthesis of the relevant chiral synthon/chiral auxiliary (-)-cis-aminoindan-2-ol. Chirality and optical purity wer

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

While some hetero-Diels-Alder (HDA) reactions are accelerated by either carbonyl or phosphate groups attached directly to the heterodiene moiety, the alkyl or aryl groups, on the other hand, have minimal influence. However, in this article, we demons

Starting from a 1,2-O-isopropylidene-α- d -xylofuranose derivative, a non-toxic free-radical approach for the synthesis of (+)-muscarine is reported. To this end, a stereoselective allylation reaction at the anomeric position of a respective xylofur

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
