616207-71-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 616207-71-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,6,2,0 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 616207-71:
(8*6)+(7*1)+(6*6)+(5*2)+(4*0)+(3*7)+(2*7)+(1*1)=137
137 % 10 = 7
So 616207-71-7 is a valid CAS Registry Number.

Total syntheses of Prelactone V and Prelactone B

Raghavendra,Tadiparthi, Krishnaji,Yadav

, p. 17 - 19 (2017/03/15)

The total syntheses of natural products Prelactone-V and Prelactone-B have been accomplished by a novel Chiron approach starting from D-glucose. The synthesis involves isopropylidene acetal formation of D-glucose using Poly(4-vinylpyridine) supported iodine as a catalyst, Tebbe olefination, Grignard reaction, Wittig olefination, selective mono deprotection of acetal using PMA/SiO2, hydrogenation and anti-1,3-diol formation are as key steps.

Total asymmetric syntheses of β-hydroxy-δ-lactones via umpolung with sulfur dioxide

Exner, Claudia J.,Laclef, Sylvain,Poli, Florent,Turks, Maris,Vogel, Pierre

supporting information; experimental part, p. 840 - 845 (2011/04/16)

Cyclic stereotriads and stereotetrads of the β-hydroxy-d-lactone type, e.g. prelactonesBandE, commonin polyketides and polypropionates, are prepared via SO2-induced oxyallylations of enoxysilanes with (1E,3Z)-1-(1-phenylethoxy) penta-1,3-dien-3-yl carboxylates. Using (Z)- or (E)-enoxysilanes both 4,5-cis- or 4,5-trans-d-lactones are obtained. Depending on the reduction method applied to the obtained aldol intermediates 5,6-trans or 5,6-cis-derivatives are formed. The d-lactones can be prepared in both their enantiomeric forms depending on the (1R)- or (1S)-configuration of the starting 1-(1-phenylethoxy)penta-1,3- dienes.

Application of silacyclic allylsilanes to the synthesis of β-hydroxy-δ-lactones: synthesis of Prelactone B

Sellars, Jonathan D.,Steel, Patrick G.

experimental part, p. 5588 - 5595 (2009/12/24)

Silacyclic allylsilanes generated through a silene-diene Diels-Alder cycloaddition represent versatile bifunctional reagents for organic synthesis. This is demonstrated in a short stereocontrolled synthesis of (±)-Prelactone B.
