โฆ Synopsis
The tricyclic ester 1 was transformed by a sequence of intramolecular Michael and alkylation reactions into the pentacyclic lactone 10 from which the (+)-15-desoxy derivatives of longikaurin C 2 and effusin 4 were then prepared.

The previously undisclosed stereochemistry of bicyclo[2.2.l]hept-5-ene-jn-hexanoyl-2-carboxylic acid(l.2) and related derivatives was determined by nmr analysis(3) and application of Fraser's rule(4.5). It was concluded that the compound in question Is the 3-m-n-hexanoyl-2-&-carboxyllc acid(I). This
The C15-C28 portion of altohyrtins (spongistatins) was prepared in a convergent manner from methyl (S)-3hydroxy-2-methylpropionate, D-arabitol, and diacetone-D-glucose via dithiane couplings with epoxides as the key segment coupling process.
