Abstract
Three key reactions, an efficient Ugi four-component coupling, a regiospecific, base-mediated elimination reaction, and an intramolecular nitrone/alkene [3+2] cycloaddition, were used to achieve an effective synthesis of the tricyclic molecular framework of the immunosuppressant FR901483. The outcome of a control experiment supports the idea that an internal deprotonation by an alkoxide ion is the origin of the site selectivity observed in the base-induced elimination of hydroxy mesylate 17.

Abstract
Two approaches to the aza-tricyclo dodecane skeleton of (-)-FR901483 are reported. Both routes utilized a Grignard addition to an N-acylpyridinium salt to establish the absolute stereochemistry at C-6 and a highly diastereoselective conjugate allylation reaction to form the quaternary center at C-1 of the natural product in an excellent yield. Although the desired polysubstituted piperidine intermediates were prepared regio- and stereoselectively, the construction of the C-8/C-9 bond connectivity could not be achieved. All attempts at a pinacol cyclization or an intramolecular 6-exo-tet epoxide opening were unsuccessful because of an unfavorable A(1,3) strain inherent in the molecule.

Abstract
A strategy is outlined for construction of the fungal immunosuppressant FR901483 (1). It was possible to convert 1,4-cyclohexanedione monoethylene ketal in five simple steps to iodoacetamide ketone 10, which was cyclized in good yield to the key bridged keto lactam 11 containing the A/B 2-azabicyclo[3.3.1]nonane ring system of the natural product. This intermediate could be transformed to N-Boc lactam 16, whose derived enolate underwent stereoselective hydroxylation with the Davis oxaziridine to produce alcohol 17 having the desired C-2 configuration. Compound 17 was then converted in three steps to alkoxy carbamate 20. The N-acyliminium ion derived from intermediate 20 could be alkylated in good overall yield with p-methoxybenzylmagnesium chloride to afford a 5:4 mixture of the desired PMB product 21 and the epimer 23. In an attempt to improve the stereoselectivity in this alkylation, the inverted C-4 protected alcohol N-Boc lactam 33 was prepared and its enolate was hydroxylated. Inexplicably, the product of this reaction was the undesired equatorial alcohol 34. Some model systems were investigated toward annulation of the C-ring of the natural product. It was found that homoallylic amine 40 could be cyclized with PhSCl in the presence of silica gel to generate the desired 5-endo tetracyclic product 42 in moderate yield. This cyclization protocol was also successfully applied to the actual FR901483 system 22, leading to the requisite tricycle 43.
