摘要:The present invention provides a one-pot method of preparing an unprotected α-O-glycolipid. The first step involves contacting a protected α-iodo sugar with a catalyst and a lipid comprising a hydroxy group, under conditions sufficient to prepare a protected α-O-glycolipid. The second step involves deprotecting the protected α-O-glycolipid under conditions sufficient to prepare the unprotected α-O-glycolipid, wherein the contacting and deprotecting steps are performed in a single vessel. The present invention also provides a one-pot method of preparing an unprotected β-O-glycolipid following the steps for the preparation of the unprotected α-O-glycolipid.

摘要:Provided are a solid catalyst which gives a cyclic carbonate at a high yield and a high selectivity, which is stable and which may be readily separated after reaction; and a method of industrially advantageous, inexpensive and safe production of a cyclic carbonate by the use of the catalyst. The catalyst contains an inorganic solid substance having a surface modified with an ionic substance containing a Group 15 element; or contains an ionic substance containing a Group 15 element, and an inorganic solid substance. The modifying group for surface modification of an inorganic solid substance is an ionic substance containing a Group 15 element. The ionic substance containing a Group 15 element is at least one substance selected from organic phosphonium salts, organic ammonium salts, organic arsonium salts and organic antimonium salts.
