  1,4-Silyl migration reactions. Applicability to alkyl-, vinyl-, and cyclopropylsilanes

  摘要：

  A series of silyl protected alcohols containing a tin substituent were found to undergo transmetalation followed by silyl migration from oxygen to carbon in the presence of methyllithium.

  Diastereomerically pure cyclopropyl, vinyl, and epoxy stannanes have been converted to the corresponding organolithium species and trapped with a variety of electrophiles. The stereochemistry of the products was retained throughout the transmetalation-trapping sequence. The stereochemistry of the tributyltin moiety and the carbinol side chain was shown to have a dramatic influence on the rate of transmetalation. 1,4-Silyl migrations were observed for silicon groups of varying steric bulk, and crossover experiments showed the migration was an intramolecular process. Access to silanes which are difficult to prepare was achieved.
