[作者:GAO SHUANHU; WANG QIAOLING; WANG GELIN; LOMENICK BRETT; LIU JIE; FAN CHIHWEI; DENG LIHWEN; HUANG JING; LUM LAWRENCE; CHEN CHUO,期刊:SYNLETT, 页码:2298-2310 , 文章类型: Article,,卷期:2012年-16]
- Isolated from the sponge Terpios hoshinota that causes coral black disease, nakiterpiosin was the first C-nor-D-homosteroid discovered from a marine source. We provide in this account an overview of the chemistry and bio...
- Efficient Synthesis of 2,5-Diketopiperazines by Staudinger-Mediated Cyclization
[作者:BEAGLE LUCAS K; HANSEN FINN K; MONBALIU JEANCHRISTOPHE M; DESROSIERS MICHAEL P; PHILLIPS ANGELA M; STEVENS CHRISTIAN V; KATRITZKY ALAN R,期刊:SYNLETT, 页码:2337-2340 , 文章类型: Article,,卷期:2012年-16]
- Solution- and solid-phase Staudinger-mediated cyclizations were assessed to efficiently prepare hetero-2,5-diketopiperazines from their protected azido dipeptide thioesters under microwave irradiation. Short reaction tim...
- A Facile Synthesis and Chemoselective Reactions of Dihydrothiouracils
[作者:KUMAR VARUN; KHATIK GOPAL L; PAL ANANG; PRANEETH MOHAN R; BHATTARAI SANJAY; NAIR VIPIN A,期刊:SYNLETT, 页码:2357-2362 , 文章类型: Article,,卷期:2012年-16]
- A highly efficient procedure was devised for the synthesis of 3-(3-arylthioureido)propanoic/butanoic acid and its cyclization to (3-aryl/3-aryl-6-methyl)-2-thioxotetrahydropyrimidin-4(1H)-one derivatives. Carbonyl diimid...
- Site-Selective Oxidation of Vitamin B-12 Using 2-Iodoxybenzoic Acid
[作者:CLARDYJAMES SUSAN; BERNSTEIN JAIME L; KERWOOD DEBORAH J; DOYLE ROBERT P,期刊:SYNLETT, 页码:2363-2366 , 文章类型: Article,,卷期:2012年-16]
- Reaction of vitamin B-12 (B-12) with excess 2-iodoxybenzoic acid and 2-hydroxypyridine leads to selective oxidation of the 5'-hydroxyl group of the ribose tail of B-12 in a 30% isolated yield. The acid derivative was pur...
- Stereodivergent Synthesis of D,D- and L,L-glycero-beta-allo-Heptopyranoses on a Dioxanone Scaffold
[作者:PALYAM NAGARJUNA; NIEWCZAS IZABELLA; MAJEWSKI MAREK,期刊:SYNLETT, 页码:2367-2370 , 文章类型: Article,,卷期:2012年-16]
- We report a stereodivergent synthesis of both enantiomers of glycero-allo-heptose from 2,2-dimethyl-1,3-dioxan-5-one, a readily available nonchiral scaffold, and from two different synthetic equivalents of glyoxal: dimet...
