• indolones 69. Further broadening of the substrate scope was achieved by changing the aryl substituent attached to the pyrazole ring nitrogen. For enantioenrichment of the products, the presence of a methyl group at the C3 position of the pyrazole ring was obligatory. One example was included with a phenyl

• the base DBU (1,8-diazabicyclo[5.4.0]undec-7-ene). Interestingly, a single solid chiral state from a nearly racemic mixture of this phenylglycinamide derivative was observed by so-called attrition-enhanced solid-phase enantioenrichment [18]. In order to obtain a molecule that is able to form a gel

• organogelators. Remarkably, our pure enantiomeric gelator could not be racemized in the gel phase, while racemization takes place in the self-assembled fiber state. We are currently studying this class of organogelator for the creation of responsive gels and attrition-enhanced solid-phase enantioenrichment

The simple procedures required for the purification and enantioenrichment of the resulting carbinols converts this flow process into a convenient alternative for the multigram
