The synthesis of (+)-boronolide and its 8-epimer utilizing diastereoselective propargylation of α-hydroxy aldehyde was analyzed. The synthesis process was started with D-tertaric acid converted to diethyl (2S, 3S)-2,3-O-isopropylidenetartrate. A method was established with DIBAL-H as the reducing agent at -78°C to reduce esters directly to aldehydes. Diastereoselective propargylation was shown to be used in the synthesis of structurally diverse compounds.
STEREOSELECTIVE SYNTHESIS OF METHYL (1R) TRANS- AND (1R) CIS-HEMICARONALDEHYDES FROM NATURAL TARTARIC ACID: APPLICATION TO THE SYNTHESIS OF S-BIOALLETHRIN AND DELTAMETHRIN INSECTICIDES.

Very efficient enantioselective syntheses of (1R)-trans-and cis-hemicaronaldehydes precursors of (1R)-trans chrysanthemic acid and its (1R)-cis dibromovinyl analogue starting from natural tartaric acid or D-mannitol are described.They are based on the rea

A chiral pool based synthetic strategy that leads from the readily available and inexpensive C2-symmetric tartaric acids to the chiral O-isopropylidenebenzooxazolei- a convenient precursor to the aminocyclitol core of hygromycin A as well as the chiral γ-disilyloxybutyrolactone-a pivotal intermediate to approach to the furanoside of hygromycin A.
A total synthesis of aliskiren

A total synthesis of aliskiren (20) was accomplished. A key in our synthesis was to use the symmetric trans-cisoid-trans-bis-lactone 1 as a precursor. It was expediently prepared by three different routes (Scheme 2). Appending the end groups and functional group transformations completed the synthesis (Scheme 3). Copyright
