Silanediols are being considered recently due to their good biological activities, such as HIV inhibition and inhibition of angiotensin-converting enzymes (ACE). Synthesis of silanediols needs to have various analogs of silafurans. An asymmetric synthesis of silafuran (5)-4-[2-(1,3-dioxolan-2-yl)ethyl]-2,2-diphenyl-2-silafuran containing a functional group was produced successfully in this work using the chiral catalyst ferrotan. The absolute configuration was assigned by analogy. HPLC with chiral column was use to prove the ratio of enantiomer excess. All new compounds were characterized with IR, NMR and MS spectra.
