Synthesis of the C(7)-C(20) fragment of spirotoamides A, B and C

This work describes the preparation of the C(7)-C(20) fragment of spirotoamides A to C in a very elegant fashion, achievement very high levels of stereocontrol. The synthesis has been accomplished by a sequence involving 14 steps (0.36percent overall yiel

Total synthesis of elaiolide using a copper(l)-promoted stille cyclodimerization reaction

(equation presented) Elaiolide (2) The 16-membered macrodiolide elaiolide (2) has been prepared in 20 steps from the ketone (S)-8 in 9.3% overall yield with a diastereoselectivity of 76%. Key steps included the copper(l) thiophene-2-carboxylate promoted c
