Abstract:
Proposed are the total syntheses of the steroids desogestrel and estrone, utilizing a 1,4 addition/alkylation process to install the correct stereochemistry at C8, C13 and C14 in a single-pot operation. The racemic total synthesis of desogestrel includes a successful domino anionic cyclisation leading to the formation of the steroid C and B rings in a single operation with complete stereocontrol at C9. The -keto phosphonates obtained were subsequently subjected to A-ring annelation via a multistep one-pot process. The enantioselective synthesis as well as the racemic total synthesis of estrone include a sequential C and B-ring formation through ring closing metathesis and intramolecular Heck reaction
