The protocol can be performed in one pot and is readily scalable, and has been utilized in a 25 g scale asymmetricsynthesis of cyclohexyl-fused spirobiindanediol (1 S,2 S,2' S)-5, in >99% ee and

Small molecule stimulators of steroid receptor coactivator-3 (SRC-3) and methods of their use as cardioprotective agents are provided. The small molecule stimulators are useful for promoting cardiac protection and repair and vascular regeneration after myocardial infarction. The compounds are also useful in preventing cardiac hypertrophy and collagen deposition and improving cardiac post-infarction function.
