An in situ developed Lewis acid-surfactant-SiO2-combined (LASSC) nanocatalyst was used, for the first time, as a green and effective promoting medium for the electrophilic activation of aldehydes under solvent-free and dry grinding conditions. The advantages of using the LASSC nanocatalyst include avoiding the generation of wastewater containing sodium dodecyl sulfate and the use of toxic reagents, excellent reusability of the catalyst, and obtaining a high yield of bis(indolyl)methanes.

Background: MRSA is a gram positive pathogen resistant to methicillin and other betalactam antibiotics, including penicillin, oxacillin, and declooxacillin. Statistical data suggest that as many as 19,000 people per year die from MRSA in the USA. Methods:
A one-pot synthesis of 2,2′-disubstituted diindolylmethanes (DIMs) via a sequential Sonogashira coupling and cycloisomerization/C3-functionalization of 2-iodoanilines

, p. 138 - 142 (2016/11/19)
An efficient synthesis of bis(indolyl)methanes from aldehydes with indoles through graphene oxide -catalyzed Friedel-Crafts alkylation is developed. The reaction proceeds in water by using graphene oxide as the single catalyst to provide the desired products in good to excellent yields. Also, this methodology has a broad substrate scope, and is environment friendly and cost economic.
