A series of functionalized ionicliquids (FILs) incorporated with chiral-pyrrolidine unit have been synthesized and tested as reusable organocatalysts for direct aldolreactions. FIL 1b in combination with acetic acid and water as additives could effectively catalyze direct aldolreactions of various ketone donors in high yields and the FIL catalyst was easily recycled and reused for six times with
It is a significant challenge to construct chiral metal–organic frameworks (CMOFs) by developing a facile and green preparation strategy. In this work, CMOFs were first synthesized via a mechanochemical process by combining a truncated mixed ligand strategy and defect engineering theory. The simple, green, and rapid construction strategy could solvent-freely harvest gram-scale CMOFs with a hierarchical

PdCl2/CrO3/HCl produced α,β-unsaturated ketonesfrom homoallyl alcohols, the present method provided orthogonally the β-hydroxy-methyl ketones. No overoxidation or elimination of benzylic and/or β-hydroxy groups was observed. The method could be extended to the oxidation of simple terminalolefins as well, to methyl ketones, displaying its versatility. An application to the regioselective synthesis of gingerol is
