Efficient and practical method for synthesizing optically active γ- trityloxymethyl-α-alkylidene-γ butyrolactones using ti(II)-mediated intramolecular nucleophilic acyl substitution reaction

An efficient and highly stereoselective method for synthesizing optically active γ-trityloxymethyl-α-alkylideneγ-butyrolactones having a stereodefined mono or disubstituted exocyclic double bond, starting from commercially available non-racemic glycidyl t

ENANTIOSPECIFIC TOTAL SYNTHESIS OF (-)-MEGAPHONE BY A HIGHLY CONTROLLED CONSECUTIVE 1,4- AND 1,3-ASYMMETRIC INDUCTION.

Enantiospecific total synthesis of (-)-megaphone (1) is reported.The key synthetic tactic is the use of (4S)-2Z-ethylidene-4-trityloxymethyl-butan-4-olide (6) to both establish the relative and absolute stereochemistry of the contiguous tertiary and quate
