Yadav,Narasimhulu,Vikram Reddy,Subba Reddy,Al Khazim Al Ghamdi, Ahmad
experimental part, p. 1075 - 1082 (2011/10/02)
A simple and efficient stereoselective total synthesis of 10-membered macrolide, herbarumin-III is described. The key steps involved in this synthesis are the selective terminal alkylation of ethyl acetoacetate with ethyl bromide, Sharpless epoxidation, NaBH4/Et2BOMe mediated stereoselective syn-1,3-asymmetric reduction, esterification and olefin metathesis.

(Chemical Equation Presented) The stereoselective synthesis of tetrasubstituted tetrahydrofurans and trisubstituted tetrahydropyrans bearing a sulfoxide was achieved by reductive cyclization (Et3SiH/TMSOTf) from the corresponding enantiopure hydroxy ketones protected as a dioxolane. These derivatives are easily accessible from a Reformatsky-type reaction between α-bromo-α′-sulfinyl ketones and protected α- or β-ketoaldehydes, followed by diastereoselective reduction of the resulting β-ketosulfoxide.

The present invention provides a method for inhibiting the growth of cancer cells using AHLs of the general formula CX-homoserine lactone where "X" represents a number of between 5 and 14 carbon atoms in the acyl chain of the AHL. The method comprises the step of administering to an individual an amount of an AHL effective to inhibit the growth of cancer cells. Also provided is a method for enhancing the effect of a chemotherapeutic agent comprising the step of administering to an individual the chemotherapeutic agent and an amount of an AHL effective to enhance the cancer cell growth inhibitory effect of the chemotherapeutic agent.
New insights into the reduction of β,δ-diketo-sulfoxides
Hanquet, Gilles,Salom-Roig, Xavier J.,Gressot-Kempf, Laurence,Lanners, Steve,Solladie, Guy
, p. 1291 - 1301 (2007/10/03)
New developments in the reduction of β,δ-diketo-sulfoxides, a reaction that affords important key intermediates for total synthesis, are described. We showed without ambiguity using NMR experiments, that the β-carbonyl group is totally enolised. This result is inconsistent with the previous hypothesis, which supposed the other tautomer (enolisation at the δ-position) as the major one. We propose a rationale to explain the side reactions occurring during the reduction of unprotected β,δ-diketo-sulfoxides and showed that judicious protection of the δ-carbonyl group gave all diastereoisomers of β-hydroxy-δ-ketosulfoxides.
