    Investigations of the Asymmetric Intramolecular [2 + 2] Photocycloaddition and Its Application as a Simple Access to Novel C2-Symmetric Chelating Bisphosphanes Bearing a Cyclobutane Backbone
    摘要:
    The asymmetric intramolecular [2 + 2] photocycloaddition of alpha,beta-enoates was evaluated as a simple access to the novel Ct-symmetric bisphosphanes 22 and 27 possessing a cyclobutane backbone. A source of different chiral auxiliaries for investigations of the photochemical key step was provided by the transacetalization of dialkyl tartrates 3 with the corresponding 3,3-dialkoxybutan-2-ones 4. An insight into the selection mechanism was gained by temperature dependent measurements on the irradiation of the dicinnamates 10a-d, since the corresponding Eyring diagram discloses strictly linear functions as well as an isoselective relationship. Diol 8a turned out to be a structurally optimized auxiliary in terms of chiral induction and product crystallization and was also successfully applied in the first asymmetric photodimerization of 2-indenecarboxylic acid esters. Indeed, in this case excellent diastereoselectivities were achieved, too, but head-to-tail dimers 16a and 16b were formed predominantly. Diesters 11a and 16a were converted by standard procedures into the desired enantiopure 1,4-diphosphane 22 and 1,5-diphosphane 27. Furthermore, the hitherto unknown absolute configuration of delta-truxinic acid was elucidated from a single crystal X-ray structure analysis of 11a.

  • Practical Cleavage of Acetals by Using an Odorless Thiol Immobilized on Silica
    作者:Mylène de Léséleuc、Andrew Kukor、Shaun D. Abbott、Boulos Zacharie
    DOI:10.1002/ejoc.201901239
    日期:2019.11.30
    A practical, efficient and general method was developed for the deprotection of a variety of aromatic and aliphatic acetals to their corresponding catechol or diol derivatives using thiol functionalized on silica gel. This is an application for the well‐known commercial solid‐supported thiol (Silia MetS ® Thiol). The procedure is mild and amenable to scale‐up. It does not require inert atmosphere and
