Efficient silylative kinetic resolution of racemic 2,2-dialkyl 5- and 6-membered cyclic benzylic alcohols was achieved using diphenylmethylchlorosilane (Ph2MeSiCl) or phenyldimethylchlorosilane (PhMe2SiCl) as a silyl source catalyzed by chiral guanidine. The reaction could be applied to a broad range of 2,2-dialkyl 1-indanols with good s-values, irrespective of the electronic nature of the substituent on the aromatic ring of the substrates and the type of substituent at the C2-position. In addition, several 2,2-dimethyl 6-membered cyclic and heterocyclic alcohols could be adopted in the reaction. (Figure presented.).

A palladium-catalysed, tandem cyclopropanol rearrangement and direct arylation approach for the synthesis of 1-indanones is reported. The reaction is generally high yielding, uses oxygen as the terminal oxidant and tolerates a range of functional groups on the aryl ring.
