title: Total synthesis of hyacinthacine A1 and 3-epi-hyacinthacine A1.
abstract: [reaction: see text] Total synthesis of hyacinthacine A(1) and its epimer at C3 is described. The synthesis includes a stereocontrolled carboazidation of a chiral allylsilane as a key step. C-Si bond oxidation and reduction of the azide, with ring-closure, complete the total synthesis, which establishes the absolute configuration of 3.
