Acyclic diastereoselective synthesis using tartrate ester modified crotylboronates. Double asymmetric reactions with α-methyl chiral aldehydes and synthesis of the C(19)-C(29) segment of rifamycin S

Double asymmetric reactions of the tartrate ester modified crotylboronates 1 and 2 and α-methyl chiral aldehydes are described. The reactions of the appropriate enantiomers of 1 and 2 with β-alkoxy-α-methylpropionaldehydes 11 provide adducts 12, 13, and 1

3-METHYL-γ-BUTYROLACTONE AS A SOURCE OF 2-METHYL-3-HYDROXYKETONES AND 2-METHYL-1,3-DIOLS: A SYNTHESIS OF THE C19-C27 FRAGMENT OF RIFAMYCIN S BY LINEAR ITERATION

3-Methyl-γ-butyrolactone has been employed as a source of 2-methyl-3-hydroxyketones after functioning as a template for the preparation of enantiomerically pure propionate chains.This method is exemplified by the preparation of the C19-C27 propionate frag
