https://doi.org/10.1007/978-3-662-03368-5 due to the poor reactivity of the Grignard reagent derived from 2-(bromomethyl)-1,3-dioxolane. The designed synthetic route enabled us to increase the ring size to generate the δ-lactone analogue employing Sharpless asymmetric epoxidation and ZrCl.-catalysed intramolecular acetalisation as the key steps.

Introduction to the Total Synthesis of Lactone-Containing Natural Products Using ZrCl4, greatest source of potential new pharmaceuticals. The discovery and application of new and interesting methodologies of use in total synthesis is vital to the goals of designing shorter, more elegant and ultimately more reliable syntheses of natural products and analogues.

The biological testing of these compounds revealed that none of these analogues showed any antifungal activity however, one of the analogues of malyngolide showed promising activity against MRSA with an MIC of 12.5?μg/mL.

M. Ataharul Islam,Abdullah Al-Shihalows for simple modification of the aryl group and, significantly, substrates containing sterically hindered aryl groups gave the highest levels of enantioselectivity and these aryl groups were readily installed by a Pb-mediated arylation of a β-keto allyl ester.
