Isolation and total synthesis of two novel metabolites from the fissurellid mollusc Scutus antipodes
Chand, Satish,Karuso, Peter
supporting information, p. 1020 - 1023 (2017/02/18)
There is almost no information on natural products from gastropods in the order Vetigastropoda and nothing at all for the superfamily Fissurellidae (keyhole and slit limpets), which are only partially protected from predation by their shell. Extraction of the Australian fissurellid Scutus antipodes yielded two new compounds, scutinin A [D-sorbityl hexakis(p-hydroxybenzoate)] and scutinin B [2-ethylhexane-1,3-bis(p-hydroxybenzoate)] that were identified by spectroscopic analysis and their structures confirmed by total synthesis. The compounds were found to have antimicrobial activity but no fish antifeedant activity.
Asymmetric cross- and self-aldol reactions of aldehydes in water with a polystyrene-supported triazolylproline organocatalyst
Llanes, Patricia,Sayalero, Sonia,Rodríguez-Escrich, Carles,Pericàs, Miquel A.
supporting information, p. 3507 - 3512 (2016/07/06)
A polystyrene (PS) immobilized triazolylproline has been prepared by a bottom-up approach involving co-polymerization with full regiocontrol. The resulting PS resin swells in water and has been applied to the enantioselective cross-aldol reaction and to the self-aldol reaction of aldehydes under essentially neat conditions, excellent yields and stereoselectivities being recorded.
Thermal decomposition of diethylketone cyclic triperoxide in polar solvents
Barreto, Gaston P.,Alvarez, Elida E.,Eyler, Gladys N.,Canizo, Adriana I.,Allegretti, Patricia E.
, p. 881 - 886 (2014/07/07)
The thermolysis of diethylketone cyclic triperoxide (3,3,6,6,9,9-hexaethyl- 1,2,4,5,7,8-hexaoxacyclononane, DEKTP) was studied in different polar solvents (ethanol, 2-propanol, 1-butanol, 2-butanol, 2-methyl-2-propanol, and acetonitrile). The rate constant values (kd) are higher for reactions performed in secondary alcohols probably because of the possibility to form a cyclic adduct with the participation of the hydrogen atom bonded to the secondary carbon. The kinetic parameters were correlated with the physicochemical properties of the selected solvents. The products of the DEKTP thermal decomposition in different polar solvents support a radical-based decomposition mechanism. CSIRO 2014.

An unusual dimerization of primary unsaturated alcohols catalyzed by RuHCl(CO)(PPh3)3
Doi, Takashi,Fukuyama, Takahide,Minamino, Satoshi,Husson, Guillaume,Ryu, Ilhyong
, p. 1875 - 1877 (2008/03/14)
When primary unsaturated alcohols were treated with a catalytic amount of RuHCl(CO)(PPh3)3 in benzene under reflux, dimerization reactions took place to give α-hydroxymethyl ketones as major product. The Royal Society of Chemistry 2006.
Process for the preparation of 2-ethyl-1,3-hexane diol
-
, (2008/06/13)
The invention relates to a new, technically simple but efficient process, with a good yield, for the preparation of 2-ethyl-1,3-hexane diol from n-butyraldehyde by aldol condensation in the presence of an alkali metal hydroxide or alkali earth metal hydroxide catalyst. To promote the reaction and to improve its controllability, a neutral phase-transfer catalyst is additionally used in the process according to the invention. 2-Ethyl-1,3-hexane diol is used in insecticides and, for example, in the preparation of polyesters.
