✦ Synopsis

Alkaloids extracted from the Quinine tree bark are a privileged scaffold for the development of asymmetric organocatalysts. In their Communication on page 929 ff., H. Hiemstra and co‐workers describe a novel Cinchona‐derived thiourea compound able to catalyze the Henry (nitroaldol) reaction of aromatic aldehydes with high enantioselectivities. The cover picture shows Cinchona pubescens (courtesy of Forest and Kim Starr, USA) and a typical Henry product.
