A new approach to the synthesis of a polyfunctional acylic chiral building block based on ethyl(S)-(–)-lactate
Abstract
Based on ethyl (S)-(–)-lactate, an original sequence of highly stereoselective transformations leading to (4S,5E)-4-bromomethyl-hept-5-enenitrile was developed using rearrangement of a chiral cyclopropyl carbinol as the key step.
