Synthesis of β-methoxyacrylate natural products based on box-Pd IIcatalyzed intermolecular methoxycarbonylation of alkynoles

Bis(oxazoline)-palladium(II) catalyzed carbonylation of homopropargyl alcohols afforded acyclic methoxyacrylate 2 and 6-membered lactone 3a-k in good combined yield. In the case of propargyl alcohols, 5-membered lactones 3p, 3q, 16 were obtained in moderate yields. The one-pot synthesis of kawa lactones 3a, 3r, 3s and formal synthesis of dihydroxycystothiazole A and dihydroxycystothiazole C are presented. To elucidate the stereochemistry of (+)-annularin G and (-)-annularin H, the first asymmetric syntheses of these natural products were achieved.

Synthesis of (3R,4S,5S,9S)-3,5,9-trihydroxy-4-methylundecanoic acid δ-lactone

Radical-mediated opening of a chiral trisubstituted epoxy alcohol using cp2TiCl furnished the '2-methyl-1,3-diol' moiety with the desired stereochemistry, which led to a total synthesis of (3R,4S,5S,9S)-3,5,9- trihydroxy-4-methylundecanoic acid
