Synthesis of trans(2-phenylethenyl)anthracene Supplementary Material This experiment proposal was tested by more than four hundred students of introductory organic chemistry in the last three years to illustrate a Wittig reaction1. The synthesis of a fluorescent compound increases the interest of all students for this kind of Size: 2MB. In these days, asymmetric transfer hydrogenation (ATH) is a very attractive method for synthesis of enantioenriched chiral compounds, especially fine chemicals such as drugs or agrochemicals. In this review, several topics related to the asymmetric transfer hydrogenation of ketones and cyclic or acyclic imines are discussed. Initially, the reaction mechanism of the ATH of ketones and imines Author: Ondřej Matuška, Martin Kindl, Petr Kačer.

The title chalcone compounds, C27H18O (I) and C33H20O (II), were synthesized using a Claisen–Schmidt condensation. Both compounds display an s-trans configuration of the enone moiety. The crystal structures feature intermolecular C—H⋯O and C—H⋯π interactions. Quantum chemical analysis of density functional theory (DFT) with a B3LYP/6–++G(d,p) basis set has been Cited by: 6.
Reaction of 4-anthracenyloxo-butenoic acid (1) with indole gave the corresponding butanoic acid 2. Cyclocondensation of 2 with hydrazine hydrate, phenyl hydrazine, semicarbazide and thiosemicarbazide gave the pyridazinone derivatives 3a-d. Reaction of 3a with POCl3 for 30 min gave the chloropyridazine derivative 4a, which was used to prepare the corresponding carbohydrate hydrazone Cited by: Book digitized by Google from the library of the University of California and uploaded to the Internet Archive by user :
