چکیده

Initially, lasubin II was synthesized diastereoselectively in racemic form [3]. Asymmetric syntheses of lasubin II were achieved based on stereoselective transformations of enantiomerically pure substrates [4] or, for example, via a diastereoselective aza-Diels-Alder reaction using a resolved chiral arylaldehyde tricarbonylchromium complex [5]. Recently, an enantioselectively catalyzed aza-Diels-Alder reaction [6] and a [2+2+2] cycloaddition reaction [7] were successfully used for the synthesis of enantiomerically pure lasubin II.

Concise enantioselective synthesis of (K)-lasubine II

An enantioselective synthesis of the quinolizidine alkaloid (K)-lasubine II 1 is reported. Two different pathways to the key intermediate 2 are described. The first case involving a sequence of ring rearrangement metathesis (RRM), simple functional group interconversion operations, followed by a stereoselective cross metathesis (CM) and in the second case a domino ring opening-/ring closing-/ c...

Studies toward the first stereoselective total synthesis of (±)-quinolizidine 195C and other transformations.

Starting from a thio-substituted 4-quinolizidinone, a series of C-6 alkylated derivatives with a trans C-6, C-9a relationship was synthesized. Further transformations led to the first stereoselective total synthesis of the structure proposed for (±)-quinolizidine 195C, the major alkaloid isolated from the skin extracts of the Madagascan frog Mantella betsileo. Since the spectral data of the syn...

[Synthesis and its application to the synthesis of biologically active natural products of new and versatile chiral building blocks].

This article describes a design and synthesis of new and versatile chiral building blocks and its application to the biologically active natural product synthesis. The chiral building blocks were prepared using a biocatalysis in an enantiomerically pure state. As an application of the above chiral building blocks to the synthesis of biologically active natural product, we demonstrated the diast...

A convenient allylsilane-N-acyliminium route toward indolizidine and quinolizidine alkaloids

This review relates all the results that we obtained in the field of the total synthesis of indolizidine and quinolizidine alkaloids using a strategy of the addition of an allylsilane on an N-acyliminium ion. In this paper, we describe the synthesis of racemic indolizidine 167B and chiral indolizidines: (-)-indolizidines 167B, 195B, 223AB, (+)-monomorine, (-)-(3R,5S,8aS)-3-butyl-5-propylindoliz...

A Convergent Stereoselective Synthesis of the Putative Structure of the Marine Alkaloid Lepadiformine via an Intramolecular Nitrone/1,3-Diene Dipolar Cycloaddition.

The marine ascidian Clavelina cylindrica produces a series of interesting tricyclic quinolizidine and indolizidine alkaloids that show toxicity in a brine shrimp assay.1 Cylindricines A (1), C (2), D (3), E (4), and F (5) differ only in the functionality of the methylene substituent in the fivemembered ring. Interestingly, cylindricines A and B (7) interconvert simply upon standing in solution,...
