• Polyphosphoric acids are used in organic synthesis for cyclizations and acylations; an alternative is Eaton's reagent.
• Hence, it was not necessary to do anything specific to promote the required sequence of 8π conrotatory and 6π disrotatory cyclizations (further highlighted in supplementary image); they occurred spontaneously on generation of tetraene-diol 15.
• Corey's carbenium-mediated cyclization of an engineered linear polyene to provide a tetracyclic steroid ring system, which built upon studies of cationic cyclizations of linear polyenes by the Albert Eschenmoser and Gilbert Stork, and the extensive studies of the W.
• Like tin-mediated radical dehalogenation reactions, photocatalytic reductive dehalogenation can be used to initiate cascade cyclizations.
• Natural P450s can perform several different types of chemical reactions including hydroxylations, N,O,S-dealkylations, epoxidations, sulfoxidations, aryl-aryl couplings, ring contractions and expansions, oxidative cyclizations, alcohol/aldehyde oxidations, desaturations, nitrogen oxidations, decarboxylations, nitrations, as well as oxidative and reductive dehalogenations.
• These adducts are then able to do many reactions, such as carboxylative cyclizations of propargyl alcohols and cycloadditions with aziridines to yield oxazolidinones.
