[1 + 1]-Condensation of 12-Oxo-Derivatives of Ricinoleic Acid Esters with Hydrazine Hydrate on the Route to Macrocycles

, p. 231 - 233 (2017/07/05)
The reactivities of the keto analogs of methyl ricinolate and its triglyceride with hydrazine hydrate were studied. The ester was found to be inert, which made it possible to synthesize a macrocyclic azine with a side chain hydrazone moiety from a 12-oxo-derivative.
Synthesis of enantiomerically pure 2,3,4,6-tetrasubstituted tetrahydropyrans by Prins-type cyclization of methyl ricinoleate and aldehydes

The AlCl3-catalyzed Prins-type cyclization of methyl ricinoleate (1), an enantiomerically pure renewable compound, with aldehydes such as heptanal (2a), isobutyraldehyde (2b), pivaldehyde (2c) and benzaldehyde (2d) is a simple reaction for the diastereoselective synthesis of enantiomerically pure 2,3,6-trialkyl-substituted 4-chlorotetrahydropyrans. The respective 4-hydroxytetrahydropyrans are obtained e.g. with aldehydes 2a and 2d using montmorillonite KSF/O as the catalyst. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.
Cleavage of Esters under Nearly Neutral Conditions at High Pressure. Chemo- and Regioselective Hydrolysis in Organic Solvents
Yamamoto, Yoshinori,Furuta, Toshiaki,Matsuo, Jiro,Kurata, Tetsuro
, p. 5737 - 5738 (2007/10/02)
Hydrolysis of esters proceeded at room temperature under high pressure in the presence of iPr2NEt or N-methylmorpholine using CH3CN-H2O (60:1) as the solvent.This very mild procedure enables the smooth hydrolysis of biologically important compounds such as amino esters, aliphatic unsaturated fatty esters, and β-hydroxy esters; no racemization, no isomerization, and no side reactions take place.
