On September 30, 1979, Binkley, Roger W.; Hehemann, David G. published an article.Synthetic Route of 38838-06-1 The title of the article was Photolysis of deoxyiodo sugars. And the article contained the following:

Deoxyiodo sugars, prepared from the corresponding partially protected carbohydrates by the triflate displacement process, on photolysis for 3 h in Me2CHOH in the presence of NaHCO3 using 450-W medium pressure Hg lamp and a Corex filter gave the corresponding deoxy sugars in 72-100% yield. The choice of conditions for photolysis had a dramatic effect on the product yield, e.g., irradiation of I in MeOH using unfiltered light from an Hg lamp gave a mixture of products from which II was obtained in 32% yield, while irradiation in Me2CHOH and the use of Corex filter gave 100% II.

On December 12, 2003, Verhelst, Steven H. L.; Martinez, Baltasar Paez; Timmer, Mattie S. M.; Lodder, Gerrit; Van der Marel, Gijsbert A.; Overkleeft, Herman S.; Van Boom, Jacques H. published an article.Synthetic Route of 38838-06-1 The title of the article was A Short Route toward Chiral, Polyhydroxylated Indolizidines and Quinolizidines. And the article contained the following:

In this paper, a rapid route toward functionalized bicyclic alkaloids is presented. In only three steps, an easily accessible carbohydrate derivative was converted into iodomethyl indolizidine I, which can equilibrate to the corresponding iodoquinolizidine II. We provide strong evidence that this equilibration proceeds via an aziridinium ion intermediate. Furthermore, nucleophilic substitution of the iodomethyl indolizidine as well as the aziridinium intermediate gives access to highly functionalized indolizidine and quinolizidine alkaloids. The experimental process involved the reaction of (3aS,4S,6R,6aR)-4-(Iodomethyl)-6-methoxy-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxole(cas: 38838-06-1).Synthetic Route of 38838-06-1

On April 1, 2011, Brock, E. Anne; Davies, Stephen G.; Lee, James A.; Roberts, Paul M.; Thomson, James E. published an article.Computed Properties of 38838-06-1 The title of the article was Asymmetric Synthesis of Polyhydroxylated Pyrrolizidines via Transannular Iodoamination with Concomitant N-Debenzylation. And the article contained the following:

The doubly diastereoselective “matched” conjugate addition of lithium (R)-N-but-3-enyl-N-(α-methyl-p-methoxybenzyl)amide to tert-Bu (4S,5R,E)-4,5-O-isopropylidene-2,7-dienoate (derived from D-ribose in 3 steps) and in situ enolate oxidation with (-)-camphorsulfonyloxaziridine was followed by ring-closing metathesis with Grubbs I to give a hexahydroazocine scaffold. Subsequent treatment with I2 resulted in transannular iodoamination accompanied by loss of the α-methyl-p-methoxybenzyl group to give the corresponding pyrrolizidine scaffold as a single diastereoisomer upon direct crystallization from the crude reaction mixture Further functional group manipulations enabled the preparation of (-)-7a-epi-hyacinthacine A1 (I).
