36169-68-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 36169-68-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,1,6 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 36169-68:
(7*3)+(6*6)+(5*1)+(4*6)+(3*9)+(2*6)+(1*8)=133
133 % 10 = 3
So 36169-68-3 is a valid CAS Registry Number.

Catalytic Environmentally Friendly Protocol for Achmatowicz Rearrangement

Li, Zhilong,Tong, Rongbiao

, p. 4847 - 4855 (2016)

The increasing interest in Achmatowicz rearrangement in organic synthesis calls for a more environmentally friendly protocol since the most popular oxidants m-CPBA and NBS produced stoichiometric organic side product (m-chlorobenzoic acid or succinimide). Mechanism-guided analysis enables us to develop a new catalytic method (Oxone/KBr) for AchR in excellent yield with K2SO4 as the only side product, which greatly facilitates the purification. This protocol was integrated with other transformations, leading to a rapid access to the highly functionalized dihydropyranones.

Divergent Synthesis of Dihydropyranone Stereoisomers via N-Heterocyclic Carbene Catalysis

Zhao, Changgui,Wang, Jian

, p. 1668 - 1672 (2019/02/19)

We recently developed a novel chiral N-heterocyclic carbene (NHC) catalyzed dynamic kinetic enantioselective acylation (DKEA) and dynamic kinetic diastereoselective acylation (DKDA) of Achmatowicz rearrangement products to generate useful intermediates for the further synthesis of carbohydrates. In this update, we describe a divergent NHC catalytic strategy for the stereoselective preparation of all four isomers starting from a common racemic precursor. The present report provides easy access to diverse optically pure dihydropyranones. (Figure presented.).

Two catalytic protocols for Achmatowicz rearrangement using cyclic diacyl peroxides as oxidants

Wei, Congyin,Zhao, Rong,Shen, Zhihong,Chang, Denghu,Shi, Lei

supporting information, p. 5566 - 5569 (2018/08/17)

In situ generated bromonium-catalyzed and visible-light photocatalytic Achmatowicz rearrangements of furfuryl alcohols using cyclic diacyl peroxides as oxidants are described. Both protocols feature broad substrate scope, excellent functional group tolera
