A Brief Summary of my Publications
Record 1 of 9
Author(s) : Narasimhan S; Madhavan S; Prasad KG
Title : A simple alkene-catalyzed reduction of aromatic esters to alcohols by zinc borohydride
Source : SYNTHETIC COMMUNICATIONS 1997, Vol 27, Iss 3, pp 385-390
Publisher : MARCEL DEKKER INC
Abstract : Reactivity of Zn(BH4)(2) was modified by adding cyclohexene to achieve the reduction of
aromatic esters to alcohols which reaction was not possible previously because of the mild nature of
the reagent. Functional groups like Cl and nitro were tolerated.

Title : Unusual reactivity of zinc borohydride - Reduction of amides to amines
Source : SYNTHETIC COMMUNICATIONS 1997, Vol 27, Iss 3, pp 391-394
Publisher : MARCEL DEKKER INC
Abstract : Zinc borohydride reduces secondary amides to the corresponding N-ethyl amines in excellent
yields. The reduction requires only stoichiometric quantities of hydride and does not require the
addition of any Lewis acid. The amides are isolated by simple hydrolysis of the reaction mixture.

Title : Unusual reactivity of zinc borohydride - Conversion of amino acids to amino alcohols
Source : SYNTHETIC COMMUNICATIONS 1996, Vol 26, Iss 4, pp 703-706
Publisher : MARCEL DEKKER INC
Abstract : Zinc borohydride reduces amino acids with only stoichiometric amounts of hydride to the
corresponding chiral alcohols in excellent yields in the absence of any Lewis acid.

Title : Synthesis of (3Z,13Z)-3,13-octadecadienyl acetate - Sex pheromone of synanthedon tenuis-
using readily available C-11-synthon
Source : INDIAN JOURNAL OF CHEMISTRY SECTION B-ORGANIC CHEMISTRY
Publisher : COUNCIL SCIENTIFIC INDUSTRIAL RESEARCH
Abstract : Synthesis of (3Z,13Z)-3,13-octadecadienyl acetate has been achieved from the readily
available 10-undecen-1-ol using cheaper reagents and less number of steps. In the key step alkylation
of an alkyne is performed with solid sodamide giving the product in 50% yield.
The method can be easily scaled-up.

Title : A SIMPLE, COST-EFFECTIVE SYNTHESIS OF E,Z-2,13-OCTADECADIENYL ACETATE, A MAJOR SEX-PHEROMONE
COMPONENT OF LEPIDOPTERAN PESTS
Source : INDIAN JOURNAL OF CHEMISTRY SECTION B-ORGANIC CHEMISTRY
Publisher : COUNCIL SCIENTIFIC INDUSTRIAL RESEARCH
Abstract : A simple, cost effective synthesis of E,Z-2,13-octadecadienyl acetate (1), a major sex pheromone
component of many lepidopteran pests, has been achieved in optimum number of steps using cheaper raw materials.
The strategy provides the target compound in 43% overall yield, and can be scaled up easily.

Title : CALCIUM BOROHYDRIDE - A REAGENT FOR FACILE CONVERSION OF CARBOXYLIC ESTERS TO
ALCOHOLS AND ALDEHYDES
Source : SYNTHETIC COMMUNICATIONS 1995, Vol 25, Iss 11, pp 1689-1697
Publisher : MARCEL DEKKER INC
Abstract : Calcium borohydride reduces both aliphatic and aromatic esters to alcohols completely in the presence
of alkene catalysts. The intermediate borates formed during the reduction of aromatic esters are converted to
aldehydes with aqueous NaOCl in good yields.

Title : REMARKABLE REGIOSELECTIVE HYDROBORATION OF TERMINAL ALKENES BY CALCIUM BOROHYDRIDE
Source : TETRAHEDRON LETTERS 1995, Vol 36, Iss 7, pp 1141-1144
Publisher : PERGAMON-ELSEVIER SCIENCE LTD
Abstract : Calcium borohydride is found to hydroborate unsaturated systems in the presence of ethyl
acetate. The reaction exhibits remarkable selectivity towards terminal double bonds. Several
Z-11-alken-1-ol pheromones are synthesized using this method.
