STEREOCONTROLLED SYNTHESIS OF SEGMENTS FOR THE SYNTHESIS OF TYLONOLIDE BY USING A RELATIVE 1,2-ASYMMETRIC INDUCTION

Abstract
Two precursors corresponding to the C(1)–C(9) and C(13)–C(17) portions of tylonolide were synthesized in which all the chiral centers were induced correctly from the only one stereocenter existing in 2-methy-3-trimethylsilylbut-3-enal and 2-benzyloxymethyl-3-trimethylsilylbut-3-enal, respectively.
