Calyculin synthetic studies. 2. Stereocontrolled assembly of the C(9)-C(13) dithiane and C(26)-C(37) oxazole intermediates

The C(9)-C(13) dithiane (+)-2 and C(26)-C(37) γ-amino acid/oxazole (+)-5, key building blocks for calyculin total synthesis, have been elaborated in homochiral form. Noteworthy features of the schemes include stereocontrolled generation of the C(36) steeo
