Title: Applications of (4+3) Cycloaddition Strategies to the Synthesis of Natural Products 


Abstract: (4+3) Cycloadditions and its variants have been widely applied in synthesis.  In this review article, we summarize some of more recent applications of (4+3) cycloadditions, including formal (4+3) cycloadditions, in the synthesis of natural products.  Many of these natural product targets have cycloheptanoid frameworks for which the (4+3) cycloaddition is a convergent strategy for their assembly.  Some natural product targets do not possess seven membered rings, and their syntheses have exploited the functional group endowed (4+3) cycloadducts resulting from these reactions, highlighting the utility of this methodology for the synthesis of many kinds of complex molecules.

Congratulations to Karen for her new paper in Angewandte Chemie

Title: Intramolecular (4+3) Cycloadditions of Pyrroles and Application to the Synthesis of the Core of Class II Galbulimima Alkaloids

Abstract: The first intramolecular (4+3) cycloadditions with pyrroles to generate optically-enriched cycloadducts having the nortropane substructure occurred in good yields with epoxy enolsilanes as electrophiles. Using this pyrrole cycloaddition as the key step, we have achieved the asymmetric synthesis of the BCDEF rings common to the Class II galbulimima alkaloids.

Congratulations to Elvis for his new paper in the Journal of the American Chemical Society!

Title: Synthesis and Applications of Unquaternized C-bound Boron Enolates

Abstract: A general and facile method to prepare unquaternized C-bound boron enolates by a ligand-controlled O-to-C isomerization is reported. Using this protocol, C-bound pinacolboron enolates have been isolated in pure form for the first time, and have been fully characterized by NMR spectroscopy and X-ray crystallography. In contrast to the general perception, such C-boron enolates are stable without coordinative saturation at the boron.  Moreover, C-boron enolates present reactivities that are distinct from the O-boron enolates, and their applications in C‒O and C‒C bond formations are demonstrated.

Congratulations to Yu Chen and Diana Chan for their new paper in Chemistry-A European Journal!

Title: Transannular [4+3] Cycloadditions of Macrocyclic Epoxy Ketones

Abstract: Transannular [4+3] cycloadditions of dienophiles derived from macrocyclic epoxy ketones produce fused ring systems having central cycloheptane subunits.  In some cases, base directly induced cycloisomerization of the epoxy ketones to yield the cycloadducts; in others, the epoxy ketones were transformed into their corresponding enolsilanes before undergoing cycloaddition.  Enantiomerically-enriched tricyclic arrays are obtained from cycloadditions starting from optically pure epoxy ketones.
