Enzymatic lactonization stategy for enantioselective synthesis of a tetrahydrolipstatin synthon
Sharma,Chattopadhyay
, p. 8059 - 8062 (2007/10/03)
A novel lipase-catalyzed protocol has been formulated for the simultaneous enantiocontrol of three stereogenic centers in a flexible acyclic system. This involved a porcine pancreatic lipase (PPL)-catalyzed δ- lactonization of a racemic 3,5-dihydroxy-2-alkyl ester to produce the lactone with high enantioselectivity (92.8%). The product lactone and its analogues are useful synthons for the asymmetric synthesis of various bioactive compounds, which include the potential anti-obesity compound, tetrahydrolipstatin.
Stereoselective syntheses of tetrahydroesterastin-β-lactam analogues

A total synthesis of the optically active tetrahydroesterastin-β-lactam analogue 2 using Miller's hydroxamate approach is described (Scheme 2). Significant modification of published procedures has resulted in a short and facile stereospecific preparation
