The structurally enticing antascomicin B (I), which exhibits potent immunosuppressant-antagonizing properties, has a complex polyketide structure. Key steps in its enantioselective total synthesis include a transannular catechol-templated Dieckmann reaction to assemble the challenging tricarbonyl functionality and a butanediacetal-directed allylation. This study involved multiple reactions and reactants, such as (S)-1-(((9H-Fluoren-9-yl)methoxy)carbonyl)piperidine-2-carboxylic acid (cas: 86069-86-5Name: (S)-1-(((9H-Fluoren-9-yl)methoxy)carbonyl)piperidine-2-carboxylic acid).
(S)-1-(((9H-Fluoren-9-yl)methoxy)carbonyl)piperidine-2-carboxylic acid (cas: 86069-86-5) belongs to piperidine derivatives. The piperidine moiety constitutes an important building block for the synthesis of a variety of bioactive natural products, alkaloids and other drugs. Piperidine prefers a chair conformation, similar to cyclohexane. Unlike cyclohexane, piperidine has two distinguishable chair conformations: one with the N–H bond in an axial position, and the other in an equatorial position.Name: (S)-1-(((9H-Fluoren-9-yl)methoxy)carbonyl)piperidine-2-carboxylic acid
