Abstract
Racemic 2-isoxazoline-5-carboxylate esters were reduced under mild conditions to form the corresponding primary alcohols. These alcohols were enzymically resolved by acylation with succinic anhydride in the presence of Amano AK lipase.

Abstract
We disclose the syntheses of (+)-bromodanicalipin A as well as (±)-fluorodanicalipin A. The relative configuration and ground-state conformation in solution of both molecules was secured by J-based configuration analysis which revealed that these are identical to natural danicalipin A. Furthermore, preliminary toxicological investigations suggest that the adverse effect of danicalipin A may be due to the lipophilicity of the halogens.

Abstract
A chemoenzymatic synthesis of the C(21)-C(27) fragment of the marine macrolide family of bryostatin antibiotics is presented. The approach commences from achiral starting materials and has as its crucial step the enzymatic resolution of a racemic mixture of soluble polymer-supported alcohols (syn-10 and syn-11). The immobilized lipase from Candida antarctica (Novozym 435) catalyzes the enantioselective acetylation of syn-10 (in 40% conversion and >99% ee), allowing isolation of the key intermediate (R)-14 in enantiomerically pure form following its cleavage from the poly(ethylene) glycol (PEG) scaffold. The PEG matrix is both compatible with the multipolymer enzymatic transformation and allows for rapid purification and facile NMR characterization of all intermediates throughout the synthesis.

Abstract
Nitronates 3, possessing a suitably located olefinic moiety and arising from conjugate addition of Grignard reagent 2 to nitro olefins 1, are trapped as silyl nitronates 8 which undergo a facile intramolecular 1,3-dipolar cycloaddition. The resulting N-(silyloxy)isoxazolidines 9 are readily transformed into isoxazolines 6 and 7 upon treatment with acid, thus completing the entire sequence in one pot. While cycloaddition to the five-membered carbocycles, in general, proceeds smoothly at rt in a stereospecific manner, that to the six-membered ring is sluggish and less selective. The advantages of this strategy over the intramolecular nitrile oxide cycloaddition, namely greater stereoselectivity and adaptability to one-pot conditions, have been demonstrated. Extensive NMR investigations unravelled the stereochemistry unambiguously and underscored the inadequacy of coupling constants alone in determining the stereochemistry in cyclopentane systems. The explanation advanced to account for the selectivities, in terms of subtle differences among the putative transition state geometries, is in qualitative agreement with widely accepted assumptions pertaining to 1,3-dipolar cycloadditions.
