The 9-phenylthioxanthyl (S-pixyl or S-Px) group has been investigated as a photocleavable protecting group for primary alcohols, and specifically as a 5' hydroxy protecting group for deoxyribonucleosides. Several alcohols, including the four nucleosides with protected exocyclic amino functions, were protected in very good to excellent yield by treatment of 9-chloro-9-phenylthioxanthene 3 in dry...
متن کاملFrequency of Diabetes Mellitus in Skin Tag Patients in Comparison with Control Group
Background & Aims: Diabetes mellitus is one of the most common types of chronic disease leading to serious complications such as blindness, end stage renal disease (ESRD), neuropathy and cardiac disorders. Skin tag is a common benign skin tumor that its association with impaired carbohydrate metabolism has been reported in some studies. The aim of this study was to compare the frequency of diab...
متن کاملSynthesis of 2'-O-methoxyethylguanosine using a novel silicon-based protecting group.
A short and efficient synthesis of 2'-O-methoxyethylguanosine (8) is described. Central to this strategy is the development of a novel silicon-based protecting group (MDPSCl(2), 2) used to protect the 3',5'-hydroxyl groups of the ribose. Silylation of guanosine with 2 proceeded with excellent regioselectivity and in 79% yield. Alkylation of the 2'-hydroxyl group of 6 proceeded with methoxyethyl...
متن کامل[B(OH)3]0.78[B(OH)2(OSO3H)]0.22 as a new, cheap and eco-friendly catalyst for synthesis of acylals at room temperature under solvent free conditions
[B(OH)3]0.78[B(OH)2(OSO3H)]0.22 or (BSA) was simply prepared by addition of chlorosulfonic acid to commercial boric acid at room temperature. This cheap and green solid acid was used as an efficient catalyst for synthesis of acylals from aldehydes under solvent-free conditions at room temperature.
