A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 2799-16-8, Name is (R)-1-Aminopropan-2-ol, molecular formula is C3H9NO.

Bile acid derivatives with a free carboxylic group or an oxazoline ring in the side chain and with different lengths of alkyl chains on steroid skeleton were synthetized and their antitumor activity against six human cancer cell lines was investigated. Methyl, ethyl, butyl or octyl chains were introduced stereo selectively by Grignard reaction at C-7 of acid and oxazoline, and at C-12 of oxazoline. Carbonyl group at C-12 of acid compound gave addition product only with methyl Grignard reagent, and complex mixture of products with other used reagents. Due to enolization, the C-3 carbonyl group did not participate in the Grignard reaction. Steric reasons are a main cause of this chemical behavior. Compounds with a butyl chain at the C-7 position showed very good antitumor activity with IC50 < 5 mu M. (C) 2017 Elsevier Ltd. All rights reserved. Interested yet?
