Concise synthesis of (+)-fastigiatine.
نویسندگان
چکیده
(+)-Fastigiatine was assembled in six steps from (R)-5-methylcyclohex-2-en-1-one. Intermolecular Diels-Alder reaction introduced most of the carbon atoms for the target. The two Boc-protected nitrogen atom building blocks were introduced by a Suzuki coupling and a cuprate addition. A biomimetic transannular Mannich reaction generated the two quaternary centers at a late stage. Each step builds core bonds, and combined with a minimalist protecting group strategy, this approach led to a very concise synthesis.

Pharmacological properties of some 3-substituted indole derivatives, a concise overview
Indole is a nitrogen-containing heterocycle. It is a very important motif in agriculture and pharmacy. Many compounds containing indole moiety has been isolated form nature. It is also an important part in natural alkaloids. Tryptophan is an amino acid which posses indole. 3-Sustituted indoles are the main group of its derivatives. Because the wide-spread application of 3-substituted indolic co...
متن کاملNew Strategy for the Synthesis of Morpholine Cores: Synthesis from N-Propargylamines
Functionalized morpholines have attracted much attention due to their potential biological activities. Despite the wide importance of morpholine derivatives in drug design of various pharmacological agents, the development of new approaches to their synthesis remains relatively unexplored. Given the low cost and easy availability of N-propargylamines, the synthesis of functionalized morphol...

متن کاملConcise Total Synthesis of (+)-Gliocladins B and C.
The first total synthesis of (+)-gliocladin B is described. Our concise and enantioselective synthesis takes advantage of a new regioselective Friedel-Crafts-based strategy to provide an efficient multigram-scale access to the C3-(3'-indolyl)hexahydropyrroloindole substructure, a molecular foundation present in a significant subset of epipolythiodiketopiperazine natural alkaloids. Our first-gen...
