A stable, simple to synthesise and versatile chiral alde- hyde building-block has been developed, its reactivity in Wittig, Horner-Wadsworth-Emmons and Grignard reactions investigated, and its use is demonstrated in a highly efficient synthesis of an

© 2014 The Royal Society of Chemistry. The first total synthesis of myrmicine ant alkaloid 5-epi-cis-275B′ (4) is presented. A tandem cyclisation established the entire core of the structure in a single transformation as well as the required 2,5-a

The intramolecular nitrone dipolar cycloaddition of in situ-generated nitrones such as compound 26 has been used for the synthesis of cyclic isoxazolidines 27 and 29. The regioselectivity of the intramolecular cycloaddition depends on the nature of t

Two-directional cross-metathesis of a range of α,ω dienes with a variety of electron deficient alkenes has been accomplished. It was found that the process is quite general and gives complete selectivity for the E,E-dienes, making this a very usefu

Tying the knot! The marriage of two-directional synthesis and tandem reactions allows access to twelve skeletally diverse scaffolds in just fifteen reactions. Two-directional synthesis yields a symmetrical linear “rope-like” keto-dienoate which i
