A CONCISE APPROACH TO FUNCTIONALIZED, HOMOCHIRAL PYRROLIDINONES
Autor: Mark G. Moloney, David T. Cherry, Mark J. Bamford, Mark J Beard
Acylation of O , N -acetal 1 gives excellent yields of the C-7 substituted products 2a,b . Alkylation of 2a under mild conditions gives high yields of the exo- 3 and endo- 4 substituted products in varying ratios, depending on the alkylating agent. T

Portal Vein Thrombosis after Laparoscopic Colectomy: Thrombolytic Therapy via the Superior Mesenteric Vein
Autor: Robert Feld, David A. Cherry, David L. Walters, George A. Poultsides, W Cannon Lewis, Steven T. Ruby
Publikováno v: The American Surgeon. 71:856-860
Portal vein thrombosis is a rare but well-reported complication after laparoscopic surgery. We present a case of portomesenteric venous thrombosis that occurred 8 days after a laparoscopic-assisted right hemicolectomy. Systemic anticoagulation failed

Pyrrolidinones derived from (S )-pyroglutamic acid. Part 1. Conformationally constrained glutamate
Autor: Steve Keeling, David T. Cherry, Mark G. Moloney, Jonathan H. Bailey, R. Brian Lamont, Mark J. Bamford, James Dyer
Publikováno v: Journal of the Chemical Society, Perkin Transactions 1. :2783-2792
Novel conformationally constrained pyroglutaminols and pyroglutamates are readily available using an α,β-unsaturated bicyclic lactam as a template for diastereocontrolled enolate additions in the key step; zinc enolates are particularly effective i

Functionalised pyrrolidinones derived from (S)-pyroglutamic acid
Autor: David T. Cherry, Mark J. Bamford, R. Brian Lamont, Kathryn A Statham, Mark G. Moloney, Jonathan H. Bailey, S. B. Shim, Mark J Beard
Publikováno v: Tetrahedron. 52:3719-3740
The generation of the lactam enolate derived from bicyclic lactams 2a-c, prepared from (S)-pyroglutamic acid 1a, and subsequent reaction with a range of electrophiles, is reported. Exo-diastereoselectivity is generally favoured. The deprotection of s

ChemInform Abstract: Asymmetric Synthesis of Chiral Organosulfur Compounds Using N- Sulfinyloxazolidinones
Autor: J. Bisaha, David A. Cherry, Margaret M. Faul, David A. Evans, Lino Colombo, Jon Clardy
Publikováno v: ChemInform. 23
This paper describes a new class of chiral sulfinyl transfer reagents, 4 and 5 (R = aryl, alkyl), which are readily prepared from the oxazolidinones derived from (4R,SS)-norephedrine (HX,) and (4s)-phenylalanine (HX,), respectively. These N-sulfinylo
