Pick one out of three: Acyclic and cyclic 1,2,3‐triols are silylated with exceptional site‐ and enantioselectivity by a small‐molecule catalyst to afford silyl ethers having a neighboring diol moiety. The new process is applied to the enantioselectivetotalsyntheses of three cleroindicins, natural products isolated from a plant used in China to battle malaria and rheumatism.
Secondary alkyllithium reagents bearing an OTBS group (TBS=tert‐butyldimethylsilyl) at the 3‐position can be prepared stereoconvergently through an I/Li exchange from a diastereomeric mixture of the corresponding secondaryalkyl iodides. These lithium reagents react with a range of electrophiles, including carbon electrophiles, with retention of configuration to yield various 1,3‐difunctionalized derivatives
