Synthesis of a heterocyclic receptor for carboxylic acids
摘要:
The synthesis of a tricyclic receptor having a bowl shape and three binding points for carboxylic acids has been achieved starting from readily available 1-tetralone derivatives. This host possesses a six-membered lactam moiety and a carboxamide at the end of a flexible arm. The association constant with benzoic acid and the stoichiometry of the complex have been determined using H-1 NMR dilution experiments. (C) 2000 Elsevier Science Ltd. All rights reserved.

Michaeladditions of compounds having acidic hydrogen (ketones, nitro derivatives, ethyl cyanacetate and ethyl malonate) on α,β unsaturated amides are carried out in the presence of the system CsF/Si(OCH3)4. The reaction takes place in heterogeneous medium without solvent. Final products are obtained (in good yields) without hydrolysis. Normal 1–4 addition products are obtained with tertiary α,β ethylenic
