Woerpel et al. have developed an excited approach to bis-homoallylic alcohols using carbon silanes (K. A. Woerpel et al., J. Am. Chem. Soc., 2005, 127, 2046.). The reaction is illustrated below. Please provide a detailed mechanism for the formation of A and then the final product itself. Please include 3D drawings to explain the chirality in the final product. Reference: K. A.
