New Strategy for Forging Contiguous Quaternary Carbon Centers via H 2 O 2 -Mediated Ring Contraction

Stereospecific construction of contiguous quaternary carbon centers constitutes a major challenge in natural product synthesis. A general protocol that enables stereospecific construction of all stereoisomers of such a moiety remains elusive. In this article, we will discuss the oxidative ring contraction of all-substituted cyclic α-formyl ketones mediated by H 2 O 2, which provides a facile access to the stereospecific construction of contiguous quaternary carbon centers.

Intramolecular Amidoalkylation of Chiral Iminium Ions: Stereoselective Synthesis of syn-1,3-Aminoalcohols

The intramolecular Hosomi-Sakurai reaction of 3-siloxybutaniminium salts exhibited a syn selectivity of up to 51:1, while the same type of reaction of 2-methyl-3-siloxypropaniminium salts showed up to 290:1 syn selectivity.
