We describe the kinetic resolution of α-silyl-substituted allylboronate esters via chiral phosphoric acid-catalyzed chemo-, diastereo- and enantioselective allylboration of aldehydes. This process provides two synthetically versatile enantioenriched compo

In this study, we disclose the catalytic addition of bi(cyclopentyl)diol-derived boronates to aldehydes promoted by chiral phosphoric acids, allowing for the formation of enantioenriched homoallylic, propargylic, and crotylic alcohols (up to >99% enantiom
Stereodivergent total synthesis of Br-nannocystins underpinning the polyketide (10R,11S) configuration as a key determinant of potency

Continuing our investigation into the structure-activity relationship of antiproliferative macrocyclic nannocystins, we describe herein total synthesis of all four stereoisomers of Br-nannocystins as well as a simplified analogue varying at the polyketide C10 and C11 positions. Biological evaluation of these compounds against PANC1 cancer cell lines showed that both the (10R,11S) configuration and its associated two substituents are crucial for high potency.
