Abstract
A Mn-catalyzed ligand-directed Csp3-Csp2 coupling of tertiary allylic alcohols with arylaldehydes has been developed. The method provides an efficient approach to access 1,5-diarylpent-1-en-3-ones via carbon-skeleton rearrangement-based aldol reaction.

Abstract
A highly stereocontrolled syn-addition of silicon nucleophiles across cyclopropenes with two different geminal substituents at C3 is reported. Diastereomeric ratios are excellent throughout (d.r.≥98:2) and enantiomeric excesses usually higher than 90 %, even reaching 99 %. This copper-catalyzed C-Si bond formation closes the gap of the direct synthesis of α-chiral cyclopropylsilanes.
