Among the fundamental chemical transformations in organic synthesis, the [3,3]-sigmatropic rearrangement occupies a unique position as a powerful, reliable, and well-defined method for the stereoselective construction of carbon-carbon or carbon-heteroatom bonds. While many other reactions can unite two subunits and create a new bond, the strengths of… (More)
A direct ruthenium-catalyzed radical chloroalkylation of N-acyl oxazolidinones capitalizing on valence tautomerism of titanium enolates has been developed. The chloroalkylation method served as the centerpiece in the enantioselective total synthesis of trichloroleucine-derived marine natural product neodysidenin.
Ring expansion reactions of strained vinylic heterocyclic substrates have attracted the attention of the synthetic community for decades. Strategic manipulations of these organic architectures enable access to many useful synthetic intermediates. This paper highlights various methods for the ring expansion of vinyloxiranes, -thiiranes, and -aziridines… (More)
Stereoselective preparation of iodoalkenes from vinylsilanes is described. 1,1,1,3,3,3-hexafluoroisopropanol serves as a unique solvent that ensures high yields and stereoselectivities in the iododesilylation of a variety of functionalized substrates.
This microreview provides a compilation of synthetic approaches and total syntheses of pinnatoxin A in a survey of the literature up to early 2010. Pinnatoxin A is the first discovered and representative member of a fascinating group of potent marine toxins that share a spiroimine subunit as a unifying structural element.
Among carbon, hydrogen, oxygen, and nitrogen, sulfur and fluorine are both leading constituents of the pharmaceuticals that comprise our medicinal history. In efforts to stimulate the minds of both the general public and expert scientist, statistics were collected from the trends associated with therapeutics spanning 12 disease categories (a total of 1969… (More)
