Amidopalladation of alkoxyallenes applied in the synthesis of an enantiopure 1-ethylquinolizidine frog alkaloid.

چکیده
A palladium-catalyzed amidation of alkoxyallenes has been developed for the construction of linear allylic N,O-acetals under basic conditions involving (cyclic) amides, sulfonamides, carbamates, and amidophosphates. Application of the methodology provided access to the enantiopure 1-ethylquinolizidine structural motif, which is a key synthon in the synthesis of the naturally occurring poisonous frog quinolizidine 233A and derivatives such as the 1-epi-isomer of quinolizidine 207I.

Total Synthesis of Alkaloid 205B
Concise and highly stereocontrolled total syntheses of racemic and enantiopure frog alkaloid 205B (1) were accomplished in 11 steps from 4-methoxypyridines 6 and 7 in overall yields of 8 and 8%, respectively. The assembly of the core of the natural product relies on a stereoselective Tsuji-Trost allylic amination reaction and a ring-closing metathesis. The synthesis features the use of an N-acy...

An approach to enantiopure hydroxylated 2H-1,2-oxazine derivatives is presented utilizing the [3 + 3] cyclisation of lithiated alkoxyallenes and an L-erythrose-derived N-glycosyl nitrone as precursors. This key step proceeded only with moderate diastereoselectivity, but allowed entry into both enantiomeric series of the resulting 3,6-dihydro-2H-1,2-oxazines. Their enol ether double bond was the...
متن کاملA practical two-step procedure for the preparation of enantiopure pyridines: Multicomponent reactions of alkoxyallenes, nitriles and carboxylic acids followed by a cyclocondensation reaction
A practical approach to highly functionalized 4-hydroxypyridine derivatives with stereogenic side chains in the 2- and 6-positions is described. The presented two-step process utilizes a multicomponent reaction of alkoxyallenes, nitriles and carboxylic acids to provide β-methoxy-β-ketoenamides which are transformed into 4-hydroxypyridines in a subsequent cyclocondensation. The process shows bro...
متن کاملPhotoassisted synthesis of enantiopure alkaloid mimics possessing unprecedented polyheterocyclic cores.
Enantiopure alkaloid mimics are synthesized via high yielding intramolecular cycloadditions of photogenerated azaxylylenes tethered to pyrroles, with further growth of molecular complexity via post-photochemical transformations of primary photoproducts. This expeditious access to structurally unprecedented polyheterocyclic cores is being developed in the context of diversity-oriented synthesis,...
