Abstract
2,6-Dideoxy sugars constitute an important class of anticancer antibiotics natural products and serve as essential medicinal tools for carbohydrate-based drug discovery and vaccine development. In particular, 2-deoxy ʟ-fucose or ʟ-oliose is a rare sugar and vital structural motif of several potent antifungal and immunosuppressive bioactive molecules. Herein, we devised a reagent-controlled stereo and chemoselective activation of ʟ-fucal, enabling the distinctive glycosylation pathways to access the rare ʟ-oliose and 2,3-unsaturated ʟ-fucoside. The milder oxo-philic Bi(OTf)3 catalyst induced the direct 1,2-addition predominantly, whereas B(C6F5)3 promoted the allylic Ferrier-rearrangement of the enol-ether moiety in ʟ-fucal glycal donor, distinguishing the competitive mechanisms. The reagent-tunable modular approach is highly advantageous, employing greener catalysts and atom-economical transformations, expensive ligand/additive-free, and probed for a diverse range of substrates comprising monosaccharides, amino-acids, bioactive natural products, and drug scaffolds embedded with susceptible or labile functionalities.

Abstract
The first total syntheses of four stereoisomers of 13-hydroxy-14-methylhexadecanoic acid have been accomplished. Central to this strategy are asymmetric alkynylation of aldehyde, acid-catalyzed lactonization, the selective protection of primary alcohol and Wittig reaction. The product 1a was obtained in 17 steps in 2% overall yield. Moreover, these synthetic chiral hydroxy fatty acids 1a-1d are valuable for the development of antibacterial agents.

Abstract
The patellazoles are a family of complex marine macrolides that exhibit potent cytotoxicity against cancer cell lines. However, despite extensive characterisation efforts, their full stereochemical assignment has remained elusive. We report our approach towards the synthesis-enabled structural elucidation of patellazole B (4), a 24-membered macrolide with 16 stereocentres and a signature thiazole-containing side chain. Our plan hinges upon isolating the unknown stereocentres into a single C20-C25 fragment to facilitate the flexible assembly of various possible diastereomers of an advanced C1-C25 fragment. Towards this end, a highly convergent and modular synthesis of one candidate diastereomer 37, corresponding to the patellazole B macrocyclic skeleton, has been achieved based on the strategic application of stereocontrolled aldol methodology, combined with Suzuki and Heck cross-coupling reactions.

Abstract
The first total synthesis and structure revision of (-)-11β-hydroxycurvularin (1b), a macrolide possessing a β-hydroxyketone moiety, were accomplished. The β-hydroxyketone moiety in this natural product was introduced by cleavage of the N-O bond in an isoxazoline ring that was formed diastereoselectively in a 1,5-remote stereocontrolled fashion by employing intramolecular nitrile oxide cycloaddition.
