1,3-Dioxolane Formation by Nucleophilic Attack of Diazoalkanes on the Peroxide Bond of 1,2-Dioxetanes
Adam, Waldemar,Treiber, Alexander
, p. 840 - 844 (1994)
The reaction of the 1,2-dioxetanes 1a-d with the diazoalkanes 2α-η was investigated.The two 3,3-disubstituted (3,3-dimethyl- and 3-(bromomethyl)-3-phenyl) dioxetanes (1a and 1b), trimethyldioxetane (1c) and tetramethyldioxetane (1d) gave with the various diazoalkanes 2 the corresponding 1,3-dioxolanes 3 (insertion products) and/or the dioxetane-derived ketone 4 (fragmentation).Nucleophilic attack by the negatively charged carbon pole of the diazoalkane on the sterically less hindered site of the dioxetane peroxide bond affords the 1,3-dioxolane 3 after cyclization with denitrogenation of the resulting O,N dipole.The O,C dipole, formed by the nucleophilic attack of the negatively charged nitrogen pole on the dioxetane, is proposed as precursor to the ketones 4 through Grob-type fragmentation with regeneration of the diazoalkane.

In straitened circumstances: In an asymmetric version of the acid-catalyzed acetalization of aldehydes, a novel member of the chiral confined Bronsted acid family significantly outperformed previously established catalysts, providing cyclic acetals with e

, p. 690 - 697 (2007/10/02)
The use of (CF3SO3)2 as a catalyst for the acetalisation of a variety of aldehydes and ketones and for trans-acetalisation is described.It is also shown that (CF3SO3)2 is at least as effective as the corresponding Pd compound, while much lower reaction rates are observed with
