✦ Synopsis


A convergent synthesis of the spiroketal subunit of rutamycins A and B has been devised via Julia coupling of sulfone 14 with aldehyde 23; the pentahydroxy ketone 3 derived from 25 underwent spontaneous cyclization to spiroketal 4.

The asymmetric synthesis of the spiroketal fragment of mtamycin B is reported employing allylsilane bond construction methodology for the introduction of five of the eight stereogenic centers. In this paper, the construction of the CI9-C28 and C29-C34 fragments as well as their coupling through an a
