Toward a total synthesis of an aglycone of spiramycin; preparation of a C-10/C-15 fragment
摘要:
Esters of the dienyl iodide 2a, which was obtained stereoselectively from the corresponding tin derivative 2b, were shown to condense with i-butyraldehyde in the conditions of the Kishi-Nozaki-Takai reaction without alteration of the E,E configuration of the butadiene moiety.
