Liu, Hui,Pinto, B. Mario
, p. 1351 - 1362 (2006)
Four series of analogues of the naturally occurring glucosidase inhibitor salacinol were synthesized for structure-activity studies with different glycosidase enzymes. The target zwitterionic compounds were synthesized by means of nucleophilic attack at t

The invention relates to a nucleating agent of formula (I), wherein residues R1 and R2 are independently selected from substituted phenyl groups, wherein the substituents of said substituted phenyl groups are independently from each other selected from the group consisting of (C1-C4)-alkyl-; and wherein R3 is a -C(O)OR4, -C(O)NR4R5, or -C(O)-NR7-NR5R6 residue, wherein R4, R5, R6, and R7 are independently from each other hydrogen or (C1-C4)-alkyl-.

A simple and undemanding synthesis of (2S,3R,4R,5R)-nonadecane-1,2,3,4,5-pentol and (2S,3R)-heptadecane-1,2,3-triol as novel C19 and C17 analogues of C18-guggultetrol was achieved by using l-ascorbic acid as a chiral pool.

The first total synthesis of the macrolactone antibiotic branimycin (4) has been described. The key disconnection leads to a cis-dehydrodecalone core and a polyketide side chain which are connected via organometallic addition. The dehydrodecalone core was targeted via altogether five different approaches featuring various kinds of chiral elements and ring-closing methodology. In the end the most successful method starting from diepoxynaphthalene 109 was chosen to carry on with the synthesis. Thus the oxygen functions and carbon appendages were introduced via organometallic desymmetrization reactions to generate epoxy ketone 107, to which vinyl iodide 11 was added after conversion into the organolithium species. The synthesis was completed by introducing the ester side chain via Michael addition and subsequent macrolactonization. Competitive approach: The first total synthesis of the macrolactone antibiotic branimycin is described (see figure). The dehydrodecalin core was targeted via five competing approaches featuring various kinds of chiral elements and ring-closing methodology. In this "Darwinian" struggle the most successful route emerged and led to the completion of the synthesis. Copyright
