Chemical Equation presented A general steroid synthesis Is presented that relies on prior formation of three stereogenlc centers (C8, C13, and C14) on a D ring template, followed by C- and B-ring cyclizatlons. The assembly of the key D ring template, achieved by a 3-component conjugate addition/alkylation process, allows Introduction of structural variety as required. The method Is illustrated by the total synthesis of estrone via a C-ring closing metathesis and a B-ring Heck cyclization.
