Boron‐catalyzed environmentally benign dehydrative Friedel‐Crafts alkylation of indole/pyrrole and aniline derivatives with β‐hydroxyl ketones has been developed for the first time. This method provides an efficient and green replacement of toxic and unstable methylvinylketone (MVK) by safer and cheaper β‐hydroxyl ketone. The reaction features easy operation, wide substrate scope and significantly, only water
Albumin-controlled stereoselective reduction of 1,3-diketones to anti-diolsElectronic supplementary information (ESI) available: Scatchard and Lineweaver–Burk plots. See http://www.rsc.org/suppdata/cc/b2/b200474g/
An unprecedented combination of high chemo- and stereoselectivity in the NaBH4 reduction of 1:1 complexes between albumin and aromatic 1,3-diketones results in the formation of anti 1,3-diols with de up to 96%.
