A concise, efficient and modular approach to the tylophora alkaloids is described, a family of potent cytotoxic agents that are equally effective against drug sensitive and multidrug resistant cancer cell lines. The advantages of the chosen route are

A full account of the development of the first catalytic manifold for the additions of allylboronates to aldehydes is described. The thermal additions (both diastereospecific and enantioselective) of 2-carboxyester 3,3-disubstituted allylboronates 1

Bor- und Silicium-Allylierungsreagentien sind bei stereokontrollierten Synthesen zwar weit verbreitet, ihre Anwendung unterliegt aber einer Reihe von Einschrankungen, die ihre Weiterentwicklung als Synthesereagentien fur nucleophile Additionen an Car

The [4+2] cycloaddition of ortho -boronoanilide dienophile 4 with cyclopentadiene was found to proceed faster than both its para isomer 8 and the unsubstituted derivative 6 , thereby confirming that self-activation by internal coordination is operati

A series of 1,n-dioxa[n](2,7)pyrenophanes (n = 7−12) with increasingly nonplanar pyrene moieties was synthesized by a 9−10 step sequence starting from 5-hydroxyisophthalic acid. The crystal structure of each member of this series was determined c

Themostdistortedpyrenemoietyyetprepared (see picture) has been synthesized by the valence isomerization of a tethered [2.2]metacyclophane-1,9-diene to a 10b,10c-dihydropyrene and in situ dehydrogenation by 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (D

In spite of their inherent isomerization tendency and low reactivity, 1-alkoxycarbonyl vinylcopper(I) intermediates from the conjugate addition of organocuprates onto acetylenic esters were trapped with very high cis-addition selectivity with iodomet

A general and efficient route to 2-substituted 1,3-cyclopentadiones 3 has been developed. This operationally simple, two-step procedure is amenable to multigram scale preparations of these useful synthetic intermediates. These compounds are then tran
