  The structure elucidation and enantioselective total synthesis of the potent HMG-CoA reductase inhibitor FR901512 were accomplished. FR901512 was prepared in 15 steps from the commercially available 2-bromo-4-methylbenzaldehyde via FR901516 in 16.3% overall yield (89% average yield). The catalytic asymmetric Nozaki−Hiyama reactions developed by us proved their applicability and reliability through

  The simple and induced diastereoselectivity of the intramolecular hetero-Diels-Alder reaction of the alkylidene 1,3-dicarbonyl compounds 7a-e, obtained in situ by Knoevenagel condensation of the aldehydes 5a-e and dimethylbarbituric acid 6, was investigated experimentally and theoretically. In all examples the selectivity is very high; thus the domino reaction of 5a and 6 gives nearly exclusively the trans-fused tricyclic dihydropyran 8 (trans/cis = 98.8:1.2). In the similar reactions of the chiral aldehydes 5b-e and 6 the trans-cycloadducts 28, 33, 36, and 41 are the main products out of four possible diastereomers. The induced diastereoselectivity for the reaction of 5b and 5e with 6 is >99:1 and for the reaction of 5e and Sd-with 6, 95.2:3.6 and 94.1:4.7, respectively. Semiempirical AM1 calculations have been used to locate the transition structures of the intramolecular hetero-Diels-Alder reaction of 7a. The results were employed to create new parameters for the MM2-type force-field to determine the transition structures of 7b-e. The obtained data were compared with the experimental results of the cycloadditions and showed an excellent agreement.

• Synthetic studies on (+)-bucidarasin C: two diastereoselective transannular reactions producing cis-decaline derivatives that show reversal selectivity

  This manuscript describes studies on the construction of the cis-decaline core of (+)-bucidarasin C. The transannular Diels-Alder (TADA) reaction of a macrocyclic lactone successfully afforded the desired cis-decaline derivative in a stereoselective manner. On the other hand, the stereoselective transannular cascade Michael (TACM) reaction of the parent macrocyclic lactone afforded the diastereomeric cis-decaline derivative as the major product.
