Available in PDF, EPUB and Kindle. Book excerpt: Over the last three decades the importance of organosilicon chemistry has greatly increased because it has opened a number of new synthetic strategies. Silicon reagents are usually low-cost, versatile and allow a wide range of reactions. This is the first Handbook to compile essential Silicon containing reagents and makes use of the leading reagent database e-EROS. Another hot volume in the series Handbooks of Reagents for Organic Synthesis, this is a must-have resource for all synthetic chemists working in drug development and medicinal chemistry. For the selection the Editor focussed on three key synthetic approaches with the greatest impact: 1. Use of silicon as a 'temporary tether' by unifying a reactive pair of functional groups and taking advantage of their template-biased intramolecular cyclization. 2. The specific use of the silane functionality as a hetero t-butyl group, often colloquially referred to as the use of silicon as a 'fat proton'. 3. The use of the Brook rearrangement as an 'anion relay stratagem'. A new feature in this Handbook is the reagent finder, an alphabetically organized lookup table arranged by organic functionality and specific structure of the silicon atom to which it is bound.

Download or read book Application of the Prins Cyclization to a Synthesis of the Tetrahydropyran Rings of Lasonolide A written by Ruth Figueroa and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This thesis describes studies toward the synthesis of the tetrahydropyran-containing marine macrolide lasonolide A.A summary of studies done by Lee and coworkers, that led to a revision of the structure as well as its first total synthesis is presented. This is followed by a literature review of the partial and completed syntheses of lasonolide A reported by other groups. The studies presented are based on the use of a Prins cyclization as the key reaction. The cyclization uses vinylogous carbonates as the source to generate the oxocarbenium ion. Therefore, we first introduce the background that led to the development of this reaction. The Prins cyclizations were promoted using trifluoroacetic acid and the products were immediately hydrolyzed to afford in most of the cases the tetrahydropyran rings as the major product. The cyclization of alkyne derived vinylogous carbonates resulted in instability of the product to the reaction conditions. Also, formation of 5-membered ring was a competing pathway. Vinlogous carbonates derived from Z-alkenes gave the all cis-2,3,4,6-tetrahydropyran in 59-70% yield. The E-alkene derived enol ethers gave the C3 epimeric tetrahydrofuran. Inversion of the secondary alcohol in the tetrahydropyran ring was partially accomplished using a Mitsunobu reaction. This methodology led to the racemic and asymmetric syntheis of the B ring of lasonolide A. The racemic synthesis was accomplished in 8 steps from 3-buten-1-ol. An asymmetric synthesis was also accomplished in 12 steps from (R)-malic acid. The quaternary stereogenic center of the A ring of lasonolide A was constructed via C-H insertion reaction using Doyle's catalyst (Rh2(4R-MEOX)4).

Available in PDF, EPUB and Kindle. Book excerpt: Radicals and radical ions are important intermediates with wide use in organic synthesis. The first book to concentrate on reagents for the creation and use of radicals and radical ions, this new volume in the Handbooks of Reagents for Organic Synthesis series compiles articles taken from the e-eros database, on reagents for use in radical and radical chemistry, to help the chemist in the lab choose the right reagents. Reflecting the enormous growth of radical chemistry over the past ten years, this is an essential guide for all synthetic chemists.

Book excerpt: Progress coupling of substrates, toward the total synthesis of amphidinolide B1 is described. The reductive 1,3-eynes and ketones was explored. It was found to work well with simple but failed to yield intermediates toward amphidinolide B1 [images] ... The coupling of 1,3-enyne and aldehyde fragments toward the synthesis of amphidinolides G3 and H4 is also described. The entire carbon skeleton of these natural products has been prepared from this coupling and a subsequent installation of a methyl group using an indium based reagent ... [images].
