Amino groups are selectively protected in good yields by reaction with O-Alkyl S-(pyridin-2-yl)carbonothiolates in an appropriate solvent at room temperature in air. Even glucosamine, which contains multiple hydroxyl groups, is selectively N-protected in methanol.
A 4-substituted-2-oxazolidinone cyclization method
-
Paragraph 0016-0018, (2017/02/24)
The invention discloses a cyclization method of 4-substituted-2-oxazolidone. The method is implemented through the following steps: (1) acylation: acylating chiral alkamine in a toluene solvent by adopting chloro-formate in the presence of potassium carbonate, so as to obtain chiral alkamine acylate; (2) cyclization: carrying out cyclization reaction through taking PEG-400 as a phase transfer catalyst, thereby obtaining 4-substituted-2-oxazolidone. Compared with the prior art, the cyclization method disclosed by the invention has the advantages that the adopted phase transfer catalyst is low in cost and is free of risk, reacting steps are reduced, the cost is reduced, and the conditions are mild, so that the method is suitable for industrial production.

An efficient sequential intramolecular cyclization of amino alcohol carbamates followed by Cu-catalyzed cross-coupling with aryl iodides under mild conditions has been developed. The reaction occurred in good yields and tolerated aryl iodides containing functionalities such as nitriles, ketones, ethers, and halogens. Heteroaryl iodides and substituted amino alcohol carbamates were also well tolerated.

Subtle exchange: Replacement of an amide function with alkene or fluoroalkene groups provides a new class of epoxidation catalysts (see scheme). The structure-dependent catalytic behavior of these isosteric peptides provides mechanistic insights in their mode of action. (Chemical Equation Presented).

A high-yielding low-cost facile synthesis of 2-oxazolidinones chiral auxiliaries
Wu, Yikang,Shen, Xin
, p. 4359 - 4363 (2007/10/03)
The chiral aminol alcohols from reduction of amino acids with NaBH4/H2SO4 were directly treated with EtO2CCl to give the carbamates, which cyclized in the presence of traces of K2CO3 at 100-130°C under vacuum to afford chiral 2-oxazolidinones in high yields. (C) 2000 Elsevier Science Ltd.
